June 2009 Integrated Algebra Regents quick answers
June 20, 2009 am30 10:12 am
Scads of impatient munchkins out there. Instead of completing the whole thing, I’m putting up my quick version of the multiple choice answers, with a few choice comments. If you see a mistake, let me know! I’m not working with a state key.
Update: 31 - 39 (Parts II, III and IV) are now posted. Note: Feel free to try to answer other people’s questions. Note: before asking a question, read the previous comments to see if yours has already been answered
- (4) 72 minutes
- (4) 1 and 6
- (1)
- (2) 58 + sw
- (3) the favorite ice cream flavor
- (4)
(the correct translation really is:
, which the kids won’t know. So choose another problem instead?)
- (1) 6
- (2)
(vocab question. Boo, hiss. Do you want to know what empirical means? More, later)
- (3)
- (2)
- (4) 1,238,400 (they asked for the approximate speed, but did not offer that 344 m/s was approximate)
- (2) 31
- (3)
(level of difficulty far exceeds what was expected. Bad question)
- (1) 8
- (3) 84
- (4) 1/2
- (1) 202
- (1) vertex: (8, -1); axis of symmetry: x = 8
- (3) It is not a function because there are multiple y-values for a given x-value
- (1) (graph has solid, not dashed line. Shading is down (to the right))
- (2)
(you guys are supposed to restrict the denominator for the kids, even if they don’t like seeing the restriction)
- (1) y = -3x + 6
- (2)
(vocab question to hurt non-native speakers. Are we testing polynomials or grasp of English?)
- (3) 3 and -6 (why did they list the roots in descending order? and with the graph in their face?)
- (2) 2
- (3) -a + b
- (4)
- (2) 0.14
- (2)
(why was the first fraction not given in lowest terms?)
- (4) {x|
, where x is an integer} (this sort of non-standard choice drives me nuts)
Update: More answers posted: (Parts II, III and IV)

for #3, dun u actually have to divide the coefficients so shudnt it be 3 not 18?
Thank you, corrected.
I was wondering, how long will it take you to post the geometry regents answers today? and also how did you get the answers?
actually not all of them are correct so far what i have checked numbers : 9, 11 and i am not to sure of number 16, and 17 . 17 is the father i got so far .
when you divide two exponents the exponents are subtracted not divided
isnt question 21 suppose to just -5 cuz both the x’s cancel out
u cant cancel them out..
u can’t.. the X is connected with a substraction sign
No!!! NEVER cross out a part of a sum or a difference – only part of a product. That probably confused many students.
dont cancel
you could
can
wat was the area of the trapezoid?
56 inches squared
56inch
Question #3 should be answer #1…27 divided by 9 is 3x^12y^4
I’m getting different answers for #28 & #29 too…let me double check.
also, for #28, for the relative error, dun u put the diff ovr the actual, not the measured, so shudnt it be 1.261/9.261 which comes out to .136164…. which rounds to 0.14 which was choice 2?
You need to divide the error by the actual volume. I misread the question and goofed. Thanks.
formula is….
ACTUAL-MEASUREd
over ACTUAL
I also got choice #3 for number 28.
u dumb 4 sayin dat stupit retard
I mean choice #2, sorry!
Volume of the measured is 8cm and volume of the actual is 9.261. Measured minus the actual divided by the actual is .1361 = .14 rounded.
And for #29, the common denominator is 12a so you get (18/12a) – (8/12a) = (10/12a) choice (4)
They asked for simplest form, so the equivalent fraction
is correct.
thats not equivalent. 5/6a is different from 10/6a because teh numerator has no variable u cant simplify it. they are different things.
No, it’s correct because the denominator is 12a, not 6a. So you can reduce it.
tht rule only applies to addends, if the coefficient and variable r multiplying, simplifying it is correct. Also, in the beginning, the problem was 6/4a – 2/3a. You can simplify the 6/4a right off the bat to 3/2a and then the common denominator is 6a.
but it said in simplest form so 10/12a is equvalent to 5/6a
Right, so choice 2.
where r u guys getting the test? to check from i dont remember cant someone tell me where to get the test
nice thansk.
Oops missed that! Thank you!
Is there a range of answers for the line of best fit question? Some of my students used a different line than y = 5x + 25 for their line…
What a lousy question. They wanted an “eyeball” answer, so I would like to assume that the answer is yes. However… this is NYSED, and they make mistakes (so do I), but they usually refuse to fix theirs. (and deny that they were mistakes, and then deny that they mattered, etc, etc), so we’ll have to see what the rubric says…
Isn’t there a real way to calculate a line of best fit? Isn’t that beyond these kids? So why ask them to do wrong math?
Haha, I agree.
I don’t teach my kids to do a linear regression on the graphing calculator. Maybe that’s my fault, but I feel like they should do it by hand since so much of this course is all about writing equations of lines, etc. My concern with that though is that some chose different lines of best fit…I sure hope they are okay with that!!
The line of best fit can be found by inputting values into L1 and L2 and then you press STAT and press the LinReg or something
The best answer would have been like y=4.5x+29
You press STAT–>Edit–>fill in the values for x, L1 and the values for y, L2 . Then you press STAT again, go to CALC, then press LinReg. The answer comes out to y=4.5x+27.3 (rounded to the nearest tenth)
its 10/6a because 5/6a is not equivalent to 10/6a. It doesnt simplify liek that.
(6/4a) – (2/3a)
(18/12a) – (8/12a)
(10/12a)
(5/6a)
can u put up the problem too?
JMAP will post the entire exam, I’d guess on Monday? It takes a lot of work to retype, so it would be silly for me to try. And I won’t scan. But if there is one problem in particular, perhaps I could get that for you.
thnx ill check on monday..this wuz lots of help though
can you put up #15 please?? the answer of 84 doesn’t ring a bell.
It was the box and whisker plot and the question was, what is the value of the upper quartile?
was 84 the first quarter?
No, 84 was the third or upper quartile.
can u post that problem 5/6a? did it raelly ask for simplest form?
What is (6/4a) – (2/3a) expressed in simplest form?
Where can I find the exam itself?
i dont understand the relative error at allll!!!
basically, u have to take the difference between the two measurements and divide it by the correct measurement. So let’s say the question said the student measured the mass of the wood to be 3 grams but it was really 3.3 grams. you take the difference, 0.3 and divide it by the correct measurement, 3.3, and that’s your relative error.
THANKS SO MUCH…TEACHER TAUGHT IT BUT IT WUZ SO CONFUSING …THAT WUZ SO SIMPLE…THNXXXXX
how many points will u lose if u drew the best fit line but didnt do the equation of the line on the scat plot?
I would think 1 out of 3 points?
where can i get the answers for the living enviroment regents june 2009
I didn’t go into detail on how to write the equation for the line of best fit. There was a multiple choice question on a past exam. What is the best way to desribe how to write it? I won’t see the exam until Monday. Some of my students said there were things on it that I didn’t teach. Did anyone find it to be difficult?
I teach my kids to draw a straight line that includes as many points as possible from the scatter plot. Then I teach them to choose two of the points on that line and find the slope, then use that and a point to write the equation of their line.
This is my first year teaching this course and I thought it was okay. I was bummed about the empirical probability question because I taught my kids experimental vs. theoretical and only mentioned the word empirical.
Some of my kids created a cumulative frequency histogram instead of a regular histogram for #38.
what is empirical prob.
I also thought #34 was tricky…the area of the trapezoid in the circle. There were lots of little things that students could have made a mistake on and it would screwed up their answer.
Like trying to measure the lines with a ruler…GRRRR!
The formula for area of a trapezoid was on the reference sheet, took me a few minutes 2 find that out
yippees i think i got all multiple choice right.. now to hope i didnt bomb on the other parts..
i don undersn 30.. ca u help me? thanks.
Did #29 accually ask for simplest form? I don’t recall it being in the question.
29 What is
expressed in simplest form?
What was the question for number 29.
For number 30 the other ste were not equivalent (1) was an empty set, (2) was {11}, (3) was {10, 11}
where’s the actual test. the answers kind of help but i need the test to know.
Will likely be posted on jmap soon. Monday? But way too much work for me to type.
ITZ UP! THE ANSWERS FOR JUNE 2009 REGENTS ARE POSTED ON JMAP.ORG
GO TO THIS WEBSITE TO SEE ALL ANSWERS!!!!GOOD LUCK!!!!!!!

Thank You!
I think number 17 is incorret. it should be 4) 236. Check it again.
freshmen = x
sophs = x + 60
juniors = 2x – 50
seniors = 3x
x + (x + 60) + (2x – 50) + 3x = 1,424
7x + 10 = 1424
x = 202
They asked for freshmen, so 202 is correct.
Amusing? 202 freshmen, 262 sophomores, 354 juniors, 606 seniors? Something’s wrong with this picture, right? Come on SED, if you use realworld context, at least pretend to make it make sense…
Fresh is def 202.
Fresh = x
Soph = x + 60
Jr = 2x – 50
Sr = 3x
Total = 1424
x + (x + 60) + (2x – 50) + 3x = 1424
7x + 10 = 1424
7x = 1414
x = 202
Ditto on the real world… more likely the problem should have been written backwards, seniors to frosh!
Beat me to the punch.
what were the questions for 14 and 16
the one i though was confusin, was the one [i dont really remember it], but it was like on interest rate i think. he had 5000 and 3/4% rate, something like that and they were asking you how much money he would have in 3 years. they also asked you to leave the answer to the nearest cent. what was the answer, and how did u do it?
3 3/4 % = 0.0375
100 % = 1.00
The percent value after one year,
converted into decimals is 1 + 0.0375 = 1.0375
Each year interest compiles,
you must multiply the previous value by 1.0375
So for three years, the equation looks like:
5000(1.0375)^3 = ~$5583.86
it’s ($5000)(1.0375) exponent 3
Was that a 2/3/4 pt question?
how is # 29 2) 5/6a???
you get 10/12a but thats not in the simplest form it is 5/6a
annnddd wat was the question to #14))???
#13 doesnt exceed difficulty all u do is factor nd solve idiots =P
ANd isnt 29 10/12a……on teh test it wasnt in simplified form….who put these answers up?
Someone with the test in front of him. You are relying on memory.
You were rude in your first message (#13 may have been easy for you, but many students did not learn how to do it). Now, in the face of a mistake, you are indignant and ready to blame others?
It’s ok to be proud you did well, but try not to be boastful. And a little more consideration for those with less knowledge than you would be a good thing.
thank you jd, for all you’ve done, but i have to agree with the above comment
#29 was 6/4a – 2/3a
so when you find a common denominator (12a), you get 18/12a – 8/12a
so, you get 10/12a, but that cannot be simplified because they are unlike terms
correct me if i’m wrong
Unlike terms cannot be added or subtracted, but you can always multiply or divide numerical coefficients. 10/12 reduces to 5/6 and the variable a stays in the denominator.
also, if you substitute any number for a, lets say 2, into both 10/12a and 5/6a, you still end up with the same value in both fractions
it sed to give the answer in simplest form!!!!!!!!!!!1
wat was the question to number 14??
Which value of x is in the solution set of
?
I am so dumb! (sort of) I got them all right, except for the box and whisker one. I had (3) 84 first, then checked my work and put (4) 94! Argh. Of all the questions to get wrong, that one! Oh well, I was really hoping for a hundred. :/
what were the answer choices for number 14???
yooooooooooooooooooo i need the damn test numb 29 is 4 u piece of
#19 should be 4 because functions cannot have mutiple X-VALUES for a singular Y-VALUE.
whoops sorry i just relized that mutiple y-values wouldn’t pass the verticle line test…..sorry
Sorry, no.
is a quadratic function
(-3,9) and (3,9) are both points on that graph, one y value, but multiple x-values.
i agree about number 19! it should be 4 not 3~!!!
Are multiple choice questions worth 2 points? Are all the anwers on your original answer key correct? Thanks for your help.
Are multiple choice questions worth 2 points and are the answers on your original answer key on this site all correct? Thanks for your help.
what question # was the expontential growth?
yes MC are worth 2 points. i believe the percent growth question was 34 but i’m working from memory.
so a 3pt question?
if it was Q34 it would be 3 pts, yes.
wasnt 28 .16 becuase the measurement of one side of the cube was 2 but the actual was 2.1 and 2 cubed is 8 and 2.1 cubed is 9.261 and 9.261 -8 = 1.261 which divided by 8 is .1576… which rounds to .16 and for the line of best fit i put y=x +25 do you think that would get credit
thanx in advance
you need to divide by the actual (2.1)^3 not the measured (8).
y = x + 25 might get 2/3 points – we won’t know until we see the rubric.
thank you so if those two are the only ones i got wrong my grade would be a 96 right
If you only lost 3 points you would get a 96 yes.
thanx i was really hoping for a hundred my teacher i was capable but hey you cant be perfect
all the time
can someone please post the values for the table about prom tickets please
no u have to divide it by the actual
what was question #23?
23 was subtracting two polynomials but you had to subtract the first from the second it took two trys to finally get it right
is there anyway i can get the exam can someone please scan it or type it up i couldnt sleep last night pleeeeeeese i would greatly appreciate it
what were the polynomials for Q23
The prom question pleease the line of best fit I got 5/4 for the slope can someone post the entire question pleeeeeeese
PLEASEE PLEASEE POSTTT SHORT ANSWERSSS!!!!!!!! thankssss
go to jmap.org and look around for the test
hey guys :D
OMG!!! I CAN’T REMEMBER ALL MY ANSWERS BUT THE ONES I DO REMEMBER, I GOT THEM ALL RIGHT!!! OMG, ONE OF THE QUESTIONS WERE TRICKY BUT I THOUGHT HARD, I DIDN’T JUST WANNA GUESS SO I PICKED AN ANSWER AND IT WAS RIGHT? OMG!!! YEY!!! THANK U 4 THE ANSWER KEY, GIVES ME EVEN MORE CONFIDENCE THAT I GOT A HIGH SCORE! WISH YAH THE BEST OF LUCK, HOPE YAH ALL PASSED!!!! x-D ;-) :-) :-D
I POSTED THIS ON AN EARLIER POST BUT I’M POSTING IT AGAIN INCASE YOU DIDN’T SEE. THE ANSWERS FOR JUNE 2009 REGENTS ARE POSTED!!!! YOU CAN CHECK YOUR ANSWERS TO SEE WHAT YOU GOT RIGHT!!!! TO MAKE IT EASIER SO YOU DONT HAVE TO SEARCH FOR IT ON THE WEBSITE, JUST CLICK THIS LINK AND IT’LL GO STRAIGHT TO IT!!!! GOOD LUCK!!!!

what was the question to 7 and 14?
# 28 is not .14 it is .15 becuse when you put the equation in the calculator you get .147……. and it says round to nearest hundreth so it is .15
no u wrong its .14 dumbass
Please refrain from bad mouthing people on this blog.
No use in tearing people down, we’re here to help and build people up!
is ur name weintraub
no i did it every possible way on my calculator and .15 is the only answer that worked
u r a dumb ass it is .15
It is so annoying that I got number 29 wrong it was a simple but tricky question.
i used the growth formula and substituted the starting amount, the rate and the number of years
can u put up question 18 14 doesnt make sense i thought it was 16
Hello! Good luck everyone on how you do.
I just have a quick question on
a-b additive inverse
i put a+b
whats the difference between additive inverse and inverse?
thanks!
Well additive inverse is just more specific. There is additive inverse which means when you add the two things you get zero and there is multiplicative inverse which means when you multiply the two things you get one. Inverse is just the general term for these two specific types. I teach my kids to think of opposites when they hear inverse.
what are the questions for 7,16 and 25?
can you please post the question to number 13?
can you post 7,9,12,14,15,22,25….they dont ring a bell….plzzz
13. Solve for a in terms of b and r.
a + ar = b + r
Factor out an a to get a(1 + r)
Divide both sides by 1 + r.
Very tough.
thanks (:
what was question # 23
u hat 2 use sin an pythagroyn therom for dat question wt da triangle rite
wat was the question for 25 and 16
#29 is 10 over 12a
#29 is 10a over 12
when there is an inequality like 2y < 2x – 2 (solving for y) when we divide by two does the inequality change to greater than rather than less than?
yes so jd2718 is wrong the correct ans is 2
The inequality sign changes ONLY when you divide or multiply by a negative number.
No, because you aren’t dividing by a negative.
#20 is wrong it was 2 shaded tp the top left because u had to divide by something and the inequality changes
You only flip the inequality sign when you divide by a negative.
wat was the area of the trapezoid on part 2???
56 inches
Does anyone have a link to the actual exam on pdf?
thanks sooo much i think i did okay “/
how many points are each multiple choice worth and what mark do you need to get a passing grade/
Each multiple choice is 2 points.
You need 30 points to pass.
hey cud u plz post the questions to numbers 7,8,12,14,15,25
did you have to write an equation for the line of best fit? I made one but didn’t write an equation for it.
did u have to write an equation for the line of best fit cuz I made a line of best fit but did not write an equation.
Aaron, u only need to get 15 right mult choice right and everything else completely wrong to pass. I really want to get a 95 though, I know I got 1 mult choice wrong, and I need to know if u needed to write an equation for your line of best fit.
Yes, you needed to write an equation for the line of best fit.
Does anyone the ability and willingness to scan and post the actual exam?
As a parent of an eighth grader who took this test, I am very frustrated with the grading scale. It appears that the percentage scores are fairly accurate if a student scores in the 90s, but the overwhelming curve continues to increase as the grades drop lower. If I calculated it correctly, a student that answered 60% of the test correctly would receive a score of 80. I know that regents are calculated into final GPAs, but I am wondering how much colleges consider the actual regents scores. Do any of the teachers know? I am hopeful that my child scored in the 90s, as he has a high 90s average in the class, but I am really disappointed with the inaccurate grading system the state uses. This year is our first experience with regents (algebra and earth science).
What were the questions for number 7 and 12
What are the questions for 16 & 25?
JD, When are the short answers coming?
By 10, Sunday AM. Probably earlier.
TY!
mr. w is yor name weintraub
souldnt #20 be shaded to the left
when u divide or multiply an inequality u switch the sign around
Why?
If 10 > 6 and we divide both sides by 2,
5 > 3.
No need to flip anything around
in this case u r dividing the 3 to isolate the y
thats what my math teacher taught us
She’d probably disagree. Sometimes we do reverse the inequality, but not all the time.
That’s why picking a sample number to check is so important, esp if you don’t always remember the rule.
i think that the rule only applies to inequalities wich can be equal to
not more than or less than
sorry i am wrong u only reverse when it is divide by a negative
if u switch sign aruond then its shaded to the left
only if it is equal to or less than or more than inequality
you flip the sign if you divide by a negative number
for the error in measurement, # 28 i think, i got choice 4. i did 2.1*2.1*2.1 minus 2*2*2 over 2.1*2.1*2.1 and i got something that rounded up to 16-isnt that how you do that problem?
please post Q23
The curve on this test is outrageous.
to high or to low
No curve for high grades and way too much for low grades
please post Q21
Which expression represents
in simplest form?
can you explain how to do this question k thanks :)
what the the question for 9?
what was question 6?
question 6 was the one were there was a sign that said”you must be at least 48 inches tall” and the question was if a persone wanted to go on the ride, express what his height would be.
please tell me what aws questions numbers 6,7,11,12,14,16,25,28
If any knows any of these questions, please post them. Thank You!
7,9,12,15,16,22,23,25 and 27
wasnt q2 “-1 and -6” because wasnt the question x^2-7x+6?
yeah but then you had to set the binomials equal to 0, so the the anwser would actually be the oppisite, which is 1 and 6.
please show the questions
relax if u go on jmap.org on monday they should have the whole eaxm and answers up…..as of right now all they hav is the conversion chart.
Yes, which is quite infuriating. For almost all of the other regents, the exam and answer key were up rather quickly.
i know its annoying….i really want to know my grade so for the past three days!! one day left.
Cuz those Regents were offered during the week. It is always the Friday afternoon test that carries over to Monday… this year it happens to be the Algebra test.
does anybody remember question 7?
what was the question for #7?
was that the question that asked where the lines cross the y axis? I couldnt remember that 1 either
tall enough to ride the ride.
that was 6
shouldnt 27 be 50.4 not 5.04 because when you multiply 12 times whatever number it was it was 50 not 5.4
Nope. When it’s powered to 10 the decimal always goes to the right of the first number.
Thanks so much for the answers!!! I’m an 8th grader and I took the regents on friday and I thought it was pretty easy, i did pretty well!!! Thanks again!!! (You are right 13 was a horrible question! I guessed. Did not get it right. oh well.) :)
Have to agree with Mary. Thanks!!!! :)
and also for 19 wouldn’t the graph not be a function because there is more than one x value for a given y value since a function is when theres only one given x value for the given y-values
mg…what was question 7…and 9
wait what was question 1
Multiple-choice (2 points)
This dudette rides on her bike to some places. In 45 minutes, she rides 5 miles. How much time would it take her to ride 8 miles then?
Use a simple proportion:
45 is equal to x
— —
5 8
45*8 = 5X
Divide 5 from both sides.
9*8=X
72=X
Thus, the dudette would have to ride for 72 minutes. WOW, that’s a long time!
Sorry – there was a mess with the proportion. I’ll have to say it in words.
45 over 5 is equal to X over 8.
That’s basically 9 equals x over 8.
9 = X/8
Multiply each side by 8.
You get 72 = X.
Same solution, either way. :) This can be used as a check.
and 7?
Dude, I can’t remember every question. LOL!
For a function, there can’t be many y-values for just one x-value. Something isn’t a function when there ARE many y-values for just one x-value. Imagine this: there are two sets – sets A and B. They each have 3 values. But the first value in set A is “connected” to two values in set B. Thus, this is not a function. You can test if something is a function or not with the vertical line test, but ONLY on graphs. In the example I just gave here, you can’t use the vertical line test because you’re dealing with sets, not a clear drawing on a graph. So, we have to be careful with this stuff, or points will be lost. I hope this cleared any confusion instead of leading to more!
yeah i did the line test and it showed that 1 x value went through more than 1 y values
So if one X-value goes through many Y-values, this means it’s not a function.
Functions can include some linear equations (not including vertical lines, obviously), parabolas, and hyperbolas.
exactly that’s why i said the answer should be there are multiple x values for a given y value not the other way around like it says. you didn’t have to explain it to me i know what a function is i was just saying that what the answer on there was wrong.
Functions EXCLUDE vertical lines, circles, ellipses, and some squares, rectangles, etc (depending on how they’re drawn on the graph).
“Scads of impatient munchkins out there. Instead of completing the whole thing, I’m putting up my quick version of the multiple choice answers, with a few choice comments. If you see a mistake, let me know! I’m not working with a state key.”
Hahaha, that’s weird. I am small in size and rather impatient. And I enjoy being called “Pipsqueak.” Coincidence? LOL!! :)
I’m so glad someone is reading! I call one of my favorites “poptart.” She is also small, and rather impatient (and not reading this, I hope. She took geometry)
“Poptart.” Hmm, that is a spunky nickname. Cool!!!
hi i would like to know why number 4 is 58+sw…..i think i put 58s+w but i forgot the question so could u please explain? thank you very much.
if someone got a 100 and someone got a 99, because of the curve, do they get the same scores?
No look at the conversion chart
number 19 is def wrong. you cant have multiple x values, because then it is not a function, they dont pass the vertical line test.
and some of those questions were more like an english test rather then a math test, i asked my teacher what empirical meant, she gave me the wrong definition because she made me get it wrong cus i changed my first answer which was right. soooo mad !
whoever got over an 87 gets a 100? thats pretty good
What are you talking about? CHeck the conversion chart
i just ignored that word and did the problem. you should get the right answer if you did that
i think #19 should be 4-cannot be function cuz multiple x-values
19, is wrong. A function is when there is multiple x values for a given y value. It’s opposite.
I think 26 is wrong. Isn’t it -a-b? Because if you put an example number say -2-1 keep change change would make it -2+-1 which s -3, the original problem was a+b 2 + 1 which is three. Add -3 and positive three together and you get 0. Right?
The opposite of a – b is b – a. Try it. 10 – 3 is 7. 3 – 10 is -7, right?
Now, b – a equals -a + b.
Didn’t it ask for the additive inverse for A + B?
Which means it’s the opposite, negative. -A-B, Keep change change is -A+ B, wouldn’t both of them be the same exact thing then?
It asked for the inverse of A – B.
A —> -A
-B —> B
Therefore: -A + B
I had taught my students that A – B = – (B – A)
Same principle, wonder if they made the connection.
For number 30, wouldn’t it be x| 10 < x < 12, because the set was {10, 12} These things "{}" were both the same. So they answer can't have two different "<" signs. ?
Sorry for different posts. I'm doing them as I'm reading them so I do not forget. Thanks for what you gave, really made me confident!
the set was{11,12}
what was the question for number 23 again?
what was 25?
19 is definitly correct-the same x value can’t equal two y values, in a circle it does.
what was Q 25? thanks
for #1 isn’t -1 AND -6?
(x-6)(x-1)
x-6=0 x-1=0
+6 +1
x=6 x=1
so ur answer would be 1 and 6 because u have to set the binomials to 0 and ur answer would be the oppisite……..im not very good at explaining things but i hope this may help you.
I remember most of my answers but i cant seem to remember question #25. If i know the question mayb i’ll remember my answer. Does anyone know what Q25 was?
Whats up wit jmap? I really want to see the regents so i can see questions and answers? Is there any way u could post it? I know its a lot of work but couldnt u scan it?
How come #1 was not (1) .89 hour ?
got my grade-95!!!
i know i got 2 mult choice wrong-#28 and 29 and my guess is i got one point off for getting the line of best fit wrong but hey, im happy!
and navah, #1 is just a proportion-6th/7th grade math
45min/5 mi=n min/8 mi
8 x 45=5 x n
360=5n
360/5=5n/5
72=n
She rode the 8 miles in 72 minutes then
hope it helps
oh! thank you so much!!
wow i was using rate(time)=distance
to find the rate and then multiplied it by 8 miles which i just realized i must’ve plugged it back into the formula wrong b/c my method would have worked but i plugged the 8 miles in as the time instead of distance….man what a stupid mistake and i spent so long looking over that one!!!
oh well i guess i couldn’t think straight for the first question of the test!!
well thanks again…im extremely happy with my mark anyway…..kay im done ranting now :)
does anyone remember question 9?
i got a 100!!!!!!!!!!!!!!!!!!!!!!!!!!!
what was question 16?
What was the question 12?
what was question #7?
isnt #19 choice 4?
that’s what I put too but i guess it’s wrong
#19 is 4 hes wrong dont worry about it
No, really, it’s 3.
A vertical line is not a function, right? Think (3,0), (3,1), (3,2), etc. lots of y values with one x value. Problem
A horizontal line is a function, right? Think (-1,5), (0,5), (1,5), (2,5), etc. Lots of x values with one y value. Good, right/
no jd your wrong because something is not a function whenever there is more than one x value paired with a y value. Not the other way around.
he isnt a function is an equation that passes the vertical line test that means that there is only one line passing through it verticaly and the y-axis is the vertical line so if it has more than one y value than it isnt a function (one x value ,more than one y value #3)
wow you do not understand that for the vertical line test when you draw the line and you see the points that the lines goes through on the graph, those points are 2 different y values but the x value is the same which means the answer would be 4 because think about it when you draw the vertical line and it goes through 2 or more points those points are going to have the same x value but different y values because an x value is always when you go across the x axis and then up which is the y value.
where are the actual regents questions? i dont happen to remember them…
how do u do #27 i got 50.4 x 10^6
exactly same here hes wrong about that question because when you multiply 12 times 5 or whatever it was you get 50.4 not 5.04.
You’re correct, when you multiply the two number you do get 50.4. But in order to make it one of those equations are are a number x10 to a power, the decimal point NEEDS to be right next to the second number, so to fully solve the problem, you need to move the decimal one to the left, and then add one to the exponent. Trust me, we went over it in class.
this regents was pretty hard
where do you get the test itself?
Uggh.. two years and I only got a 98..
omg this there anyway you can put up the questions for the exam??
they will prob. put on jmap.org soon
will the exam be on by tmw?
I POSTED THIS ON AN EARLIER POST BUT I’M POSTING IT AGAIN INCASE YOU DIDN’T SEE. THE ANSWERS FOR JUNE 2009 REGENTS ARE POSTED!!!! YOU CAN CHECK YOUR ANSWERS TO SEE WHAT YOU GOT RIGHT!!!! TO MAKE IT EASIER SO YOU DONT HAVE TO SEARCH FOR IT ON THE WEBSITE, JUST CLICK THIS LINK AND IT’LL GO STRAIGHT TO IT!!!! GOOD LUCK!!!!

Omg ty! How many points are multiple choice?
Does anyone know if you can retake the test in August, even if you passed?
yea there is on august 13….cuz if i didnt pass that was the day my hs said i would have to take it so i can be in adv math program
does anyone actually know where you can see the actual exam?
WHERE IS THE ACTUAL TEST???????????????????
http://www.jmap.org/JMAP_REGENTS_EXAMS.htm
THANKS JD
So i am taking the regents integrated algebra tomorrow, IS THIS THE same test on this site
ARE AUGUST 2009 AND JUNE2009 THE SAME REGENTS (Integrated Algebra)
The Regents are scheduled annually in January,June and August. Each test administration is a different set of questions.The exams are not identical but they cover the same “curriculum”.
The exam on this site is NOT the Aug. 2009 exam and no other site has a copy since the Regents exams are kept under lock and key. The exam is released immediately prior to the actual exam time. The exam on this site is the June 2009 exam. It was released after the embargo date and time.
Take a deep breath; repeat to yourself, “I know this stuff”, get a good night’s sleep and bring pens,pencils and a calculator(just in case one isn’t available)
Good Luck
how do u solve # 20,21,23,25
How do u solve #17?
how about 21?
yo question 2’s answer is should be number -1 and – 6 not 1 and 6 am i incorrect??
oh hiya
haha usuk
shouldnt number 22 be 2 because m=-3 which is in choice one but the y intercept is -6 not 6 so shouldnt the end of the equation which is always the y intercept be -6
Don’t you only have to get fifteen of the multiple choice questions right to pass
can u pleaz help me study for my redo regents in like 3 weeks
where can i get the worck for all of the multiple choice
