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

for #3, dun u actually have to divide the coefficients so shudnt it be 3 not 18?

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 .

June 20, 2009 am30 10:58 am 10:58 am

when you divide two exponents the exponents are subtracted not divided

June 20, 2009 pm30 8:14 pm 8:14 pm

isnt question 21 suppose to just -5 cuz both the x’s cancel out

June 20, 2009 pm30 9:28 pm 9:28 pm

u cant cancel them out..

July 1, 2009 pm31 8:09 pm 8:09 pm

u can’t.. the X is connected with a substraction sign

July 5, 2009 pm31 5:24 pm 5:24 pm

No!!! NEVER cross out a part of a sum or a difference – only part of a product. That probably confused many students.

Question #3 should be answer #1…27 divided by 9 is 3x^12y^4

June 20, 2009 am30 10:28 am 10:28 am

I’m getting different answers for #28 & #29 too…let me double check.

June 20, 2009 am30 10:30 am 10:30 am

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?

• June 20, 2009 am30 10:39 am 10:39 am

You need to divide the error by the actual volume. I misread the question and goofed. Thanks.

June 20, 2009 pm30 3:34 pm 3:34 pm

formula is….

ACTUAL-MEASUREd
over ACTUAL

June 20, 2009 am30 10:31 am 10:31 am

I also got choice #3 for number 28.

December 29, 2009 pm31 6:31 pm 6:31 pm

u dumb 4 sayin dat stupit retard

June 20, 2009 am30 10:31 am 10:31 am

I mean choice #2, sorry!

June 20, 2009 am30 10:32 am 10:32 am

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.

June 20, 2009 am30 10:34 am 10:34 am

And for #29, the common denominator is 12a so you get (18/12a) – (8/12a) = (10/12a) choice (4)

• June 20, 2009 am30 10:40 am 10:40 am

They asked for simplest form, so the equivalent fraction $\frac{5}{6a}$ is correct.

June 20, 2009 am30 10:50 am 10:50 am

thats not equivalent. 5/6a is different from 10/6a because teh numerator has no variable u cant simplify it. they are different things.

June 20, 2009 am30 10:55 am 10:55 am

No, it’s correct because the denominator is 12a, not 6a. So you can reduce it.

June 20, 2009 am30 10:59 am 10:59 am

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.

June 20, 2009 am30 10:56 am 10:56 am

but it said in simplest form so 10/12a is equvalent to 5/6a

June 20, 2009 am30 10:58 am 10:58 am

Right, so choice 2.

June 22, 2009 pm30 9:58 pm 9:58 pm

where r u guys getting the test? to check from i dont remember cant someone tell me where to get the test

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…

• June 20, 2009 am30 10:58 am 10:58 am

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?

June 20, 2009 am30 11:01 am 11:01 am

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!!

June 20, 2009 am30 11:46 am 11:46 am

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

June 21, 2009 am30 11:04 am 11:04 am

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)

June 20, 2009 am30 10:53 am 10:53 am

its 10/6a because 5/6a is not equivalent to 10/6a. It doesnt simplify liek that.

June 20, 2009 am30 10:57 am 10:57 am

(6/4a) – (2/3a)
(18/12a) – (8/12a)
(10/12a)
(5/6a)

June 20, 2009 am30 10:53 am 10:53 am

can u put up the problem too?

• June 20, 2009 am30 10:55 am 10:55 am

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.

June 20, 2009 am30 11:01 am 11:01 am

thnx ill check on monday..this wuz lots of help though

June 20, 2009 am30 11:20 am 11:20 am

can you put up #15 please?? the answer of 84 doesn’t ring a bell.

June 20, 2009 am30 11:26 am 11:26 am

It was the box and whisker plot and the question was, what is the value of the upper quartile?

June 21, 2009 am30 12:29 am 12:29 am

was 84 the first quarter?

June 21, 2009 am30 7:35 am 7:35 am

No, 84 was the third or upper quartile.

June 20, 2009 am30 10:59 am 10:59 am

can u post that problem 5/6a? did it raelly ask for simplest form?

June 20, 2009 am30 11:27 am 11:27 am

What is (6/4a) – (2/3a) expressed in simplest form?

Where can I find the exam itself?

June 20, 2009 am30 11:05 am 11:05 am

i dont understand the relative error at allll!!!

June 20, 2009 am30 11:17 am 11:17 am

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.

• June 20, 2009 pm30 8:00 pm 8:00 pm

THANKS SO MUCH…TEACHER TAUGHT IT BUT IT WUZ SO CONFUSING …THAT WUZ SO SIMPLE…THNXXXXX

June 20, 2009 am30 11:06 am 11:06 am

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?

June 20, 2009 am30 11:28 am 11:28 am

I would think 1 out of 3 points?

where can i get the answers for the living enviroment regents june 2009

June 20, 2009 am30 11:27 am 11:27 am

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?

June 20, 2009 am30 11:31 am 11:31 am

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.

June 20, 2009 pm30 2:11 pm 2:11 pm

what is empirical prob.

June 20, 2009 am30 11:33 am 11:33 am

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.

June 20, 2009 pm30 12:09 pm 12:09 pm

Like trying to measure the lines with a ruler…GRRRR!

June 21, 2009 am30 9:27 am 9:27 am

The formula for area of a trapezoid was on the reference sheet, took me a few minutes 2 find that out

Did #29 accually ask for simplest form? I don’t recall it being in the question.

• June 20, 2009 pm30 12:09 pm 12:09 pm

29 What is $\frac{6}{4a} - \frac{2}{3a}$ expressed in simplest form?

What was the question for number 29.

June 20, 2009 pm30 12:09 pm 12:09 pm

For number 30 the other ste were not equivalent (1) was an empty set, (2) was {11}, (3) was {10, 11}

June 20, 2009 pm30 12:10 pm 12:10 pm

where’s the actual test. the answers kind of help but i need the test to know.

Thank You!

June 20, 2009 pm30 12:27 pm 12:27 pm

I think number 17 is incorret. it should be 4) 236. Check it again.

• June 20, 2009 pm30 12:34 pm 12:34 pm

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…

June 20, 2009 pm30 12:35 pm 12:35 pm

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

June 20, 2009 pm30 12:36 pm 12:36 pm

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

30. June 20, 2009 pm30 1:15 pm 1:15 pm

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?

June 20, 2009 pm30 1:36 pm 1:36 pm

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 31. linda Cohen permalink June 20, 2009 pm30 1:33 pm 1:33 pm it’s ($5000)(1.0375) exponent 3

June 20, 2009 pm30 1:44 pm 1:44 pm

Was that a 2/3/4 pt question?

how is # 29 2) 5/6a???

June 20, 2009 pm30 8:36 pm 8:36 pm

you get 10/12a but thats not in the simplest form it is 5/6a

annnddd wat was the question to #14))???

June 20, 2009 pm30 1:54 pm 1:54 pm

#13 doesnt exceed difficulty all u do is factor nd solve idiots =P

June 20, 2009 pm30 1:55 pm 1:55 pm

ANd isnt 29 10/12a……on teh test it wasnt in simplified form….who put these answers up?

• June 20, 2009 pm30 1:59 pm 1:59 pm

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.

June 20, 2009 pm30 3:05 pm 3:05 pm

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

June 20, 2009 pm30 3:54 pm 3:54 pm

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.

June 20, 2009 pm30 6:01 pm 6:01 pm

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

yooooooooooooooooooo i need the damn test numb 29 is 4 u piece of

June 20, 2009 pm30 2:28 pm 2:28 pm

#19 should be 4 because functions cannot have mutiple X-VALUES for a singular Y-VALUE.

June 20, 2009 pm30 2:32 pm 2:32 pm

whoops sorry i just relized that mutiple y-values wouldn’t pass the verticle line test…..sorry

• June 20, 2009 pm30 2:33 pm 2:33 pm

Sorry, no.
$y = x^2$ is a quadratic function

what question # was the expontential growth?

44. June 20, 2009 pm30 2:42 pm 2:42 pm

yes MC are worth 2 points. i believe the percent growth question was 34 but i’m working from memory.

June 20, 2009 pm30 2:44 pm 2:44 pm

so a 3pt question?

• June 20, 2009 pm30 2:46 pm 2:46 pm

if it was Q34 it would be 3 pts, yes.

June 20, 2009 pm30 2:43 pm 2:43 pm

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

46. June 20, 2009 pm30 2:49 pm 2:49 pm

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.

June 20, 2009 pm30 2:52 pm 2:52 pm

thank you so if those two are the only ones i got wrong my grade would be a 96 right

• June 20, 2009 pm30 2:58 pm 2:58 pm

what was the question to 7 and 14?

June 20, 2009 pm30 4:54 pm 4:54 pm

# 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

June 20, 2009 pm30 5:22 pm 5:22 pm

no u wrong its .14 dumbass

is ur name weintraub

June 21, 2009 am30 8:15 am 8:15 am

no i did it every possible way on my calculator and .15 is the only answer that worked

June 21, 2009 am30 8:43 am 8:43 am

u r a dumb ass it is .15

June 20, 2009 pm30 5:27 pm 5:27 pm

It is so annoying that I got number 29 wrong it was a simple but tricky question.

June 20, 2009 pm30 5:57 pm 5:57 pm

i used the growth formula and substituted the starting amount, the rate and the number of years

June 20, 2009 pm30 6:11 pm 6:11 pm

can u put up question 18 14 doesnt make sense i thought it was 16

June 20, 2009 pm30 6:33 pm 6:33 pm

Hello! Good luck everyone on how you do.

I just have a quick question on

i put a+b

whats the difference between additive inverse and inverse?

thanks!

June 20, 2009 pm30 8:54 pm 8:54 pm

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?

June 20, 2009 pm30 6:47 pm 6:47 pm

can you please post the question to number 13?

66. June 20, 2009 pm30 8:05 pm 8:05 pm

can you post 7,9,12,14,15,22,25….they dont ring a bell….plzzz

June 20, 2009 pm30 8:15 pm 8:15 pm

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.

June 21, 2009 pm30 6:51 pm 6:51 pm

June 20, 2009 pm30 10:51 pm 10:51 pm

#29 is 10 over 12a

June 20, 2009 pm30 10:52 pm 10:52 pm

#29 is 10a over 12

June 20, 2009 pm30 11:05 pm 11:05 pm

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?

• June 20, 2009 pm30 11:07 pm 11:07 pm

yes so jd2718 is wrong the correct ans is 2

June 20, 2009 pm30 11:26 pm 11:26 pm

The inequality sign changes ONLY when you divide or multiply by a negative number.

June 21, 2009 am30 7:28 am 7:28 am

No, because you aren’t dividing by a negative.

73. June 20, 2009 pm30 11:06 pm 11:06 pm

#20 is wrong it was 2 shaded tp the top left because u had to divide by something and the inequality changes

June 21, 2009 am30 7:32 am 7:32 am

You only flip the inequality sign when you divide by a negative.

how many points are each multiple choice worth and what mark do you need to get a passing grade/

June 21, 2009 am30 7:30 am 7:30 am

Each multiple choice is 2 points.

June 21, 2009 am30 7:31 am 7:31 am

You need 30 points to pass.

did you have to write an equation for the line of best fit? I made one but didn’t write an equation for it.

June 21, 2009 am30 1:04 am 1:04 am

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.

June 21, 2009 am30 1:07 am 1:07 am

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.

June 21, 2009 am30 7:30 am 7:30 am

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?

June 21, 2009 am30 7:56 am 7:56 am

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).

June 21, 2009 am30 8:25 am 8:25 am

What were the questions for number 7 and 12

June 21, 2009 am30 8:30 am 8:30 am

What are the questions for 16 & 25?

June 21, 2009 am30 8:31 am 8:31 am

JD, When are the short answers coming?

• June 21, 2009 am30 8:35 am 8:35 am

By 10, Sunday AM. Probably earlier.

TY!

mr. w is yor name weintraub

June 21, 2009 am30 9:22 am 9:22 am

souldnt #20 be shaded to the left

• June 21, 2009 am30 9:26 am 9:26 am

$3y - 9 \leq 6x$ becomes $y \leq 2x + 3$ so you would shade down on the “less than” but also you could check a point. For example (0,0) gives -9 < 0, which works. Shade down (and to the right).

June 21, 2009 am30 10:16 am 10:16 am

when u divide or multiply an inequality u switch the sign around

• June 21, 2009 am30 10:17 am 10:17 am

Why?

If 10 > 6 and we divide both sides by 2,
5 > 3.

No need to flip anything around

June 21, 2009 am30 10:17 am 10:17 am

in this case u r dividing the 3 to isolate the y

June 21, 2009 am30 10:18 am 10:18 am

thats what my math teacher taught us

• June 21, 2009 am30 10:20 am 10:20 am

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.

June 21, 2009 am30 10:27 am 10:27 am

i think that the rule only applies to inequalities wich can be equal to

June 21, 2009 am30 10:28 am 10:28 am

not more than or less than

June 21, 2009 am30 10:31 am 10:31 am

sorry i am wrong u only reverse when it is divide by a negative

June 21, 2009 am30 10:19 am 10:19 am

if u switch sign aruond then its shaded to the left

June 21, 2009 am30 10:24 am 10:24 am

only if it is equal to or less than or more than inequality

June 21, 2009 am30 10:55 am 10:55 am

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?

June 21, 2009 am30 11:25 am 11:25 am

June 21, 2009 am30 11:26 am 11:26 am

The curve on this test is outrageous.

June 21, 2009 pm30 12:07 pm 12:07 pm

to high or to low

June 21, 2009 pm30 2:13 pm 2:13 pm

what was question 6?

June 21, 2009 pm30 4:30 pm 4:30 pm

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.

wasnt q2 “-1 and -6” because wasnt the question x^2-7x+6?

June 21, 2009 pm30 4:25 pm 4:25 pm

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.

what was the question for #7?

June 21, 2009 pm30 7:37 pm 7:37 pm

was that the question that asked where the lines cross the y axis? I couldnt remember that 1 either

• June 21, 2009 pm30 8:44 pm 8:44 pm

tall enough to ride the ride.

• June 21, 2009 pm30 9:09 pm 9:09 pm

that was 6

105. June 21, 2009 pm30 8:12 pm 8:12 pm

shouldnt 27 be 50.4 not 5.04 because when you multiply 12 times whatever number it was it was 50 not 5.4

June 22, 2009 pm30 4:15 pm 4:15 pm

Nope. When it’s powered to 10 the decimal always goes to the right of the first number.

June 21, 2009 pm30 8:13 pm 8:13 pm

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.) :)

• June 21, 2009 pm30 8:20 pm 8:20 pm

Have to agree with Mary. Thanks!!!! :)

107. June 21, 2009 pm30 8:14 pm 8:14 pm

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

• June 21, 2009 pm30 8:34 pm 8:34 pm

mg…what was question 7…and 9

June 21, 2009 pm30 8:28 pm 8:28 pm

wait what was question 1

• June 21, 2009 pm30 8:34 pm 8:34 pm

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!

• June 21, 2009 pm30 8:37 pm 8:37 pm

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.

June 21, 2009 pm30 8:39 pm 8:39 pm

and 7?

• June 21, 2009 pm30 8:45 pm 8:45 pm

Dude, I can’t remember every question. LOL!

109. June 21, 2009 pm30 8:31 pm 8:31 pm

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!

• June 21, 2009 pm30 8:36 pm 8:36 pm

yeah i did the line test and it showed that 1 x value went through more than 1 y values

• June 21, 2009 pm30 8:39 pm 8:39 pm

So if one X-value goes through many Y-values, this means it’s not a function.

• June 21, 2009 pm30 8:40 pm 8:40 pm

Functions can include some linear equations (not including vertical lines, obviously), parabolas, and hyperbolas.

• June 22, 2009 pm30 2:13 pm 2:13 pm

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.

110. June 21, 2009 pm30 8:41 pm 8:41 pm

Functions EXCLUDE vertical lines, circles, ellipses, and some squares, rectangles, etc (depending on how they’re drawn on the graph).

June 21, 2009 pm30 8:47 pm 8:47 pm

June 21, 2009 pm30 9:35 pm 9:35 pm

if someone got a 100 and someone got a 99, because of the curve, do they get the same scores?

June 22, 2009 pm30 8:01 pm 8:01 pm

No look at the conversion chart

June 21, 2009 pm30 9:42 pm 9:42 pm

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 !

June 21, 2009 pm30 9:48 pm 9:48 pm

whoever got over an 87 gets a 100? thats pretty good

June 22, 2009 pm30 8:01 pm 8:01 pm

What are you talking about? CHeck the conversion chart

June 21, 2009 pm30 9:54 pm 9:54 pm

i just ignored that word and did the problem. you should get the right answer if you did that

June 21, 2009 pm30 11:42 pm 11:42 pm

i think #19 should be 4-cannot be function cuz multiple x-values

June 21, 2009 pm30 11:54 pm 11:54 pm

19, is wrong. A function is when there is multiple x values for a given y value. It’s opposite.

June 22, 2009 am30 12:32 am 12:32 am

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?

• June 22, 2009 am30 12:36 am 12:36 am

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.

June 22, 2009 am30 12:38 am 12:38 am

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?

June 22, 2009 am30 3:27 am 3:27 am

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.

June 22, 2009 am30 12:36 am 12:36 am

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!

June 23, 2009 pm30 12:18 pm 12:18 pm

the set was{11,12}

June 22, 2009 am30 1:21 am 1:21 am

what was the question for number 23 again?

120. June 22, 2009 am30 5:48 am 5:48 am

what was 25?

June 22, 2009 am30 7:52 am 7:52 am

19 is definitly correct-the same x value can’t equal two y values, in a circle it does.

what was Q 25? thanks

June 22, 2009 am30 8:35 am 8:35 am

for #1 isn’t -1 AND -6?

June 22, 2009 pm30 2:36 pm 2:36 pm

(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.

June 22, 2009 pm30 5:18 pm 5:18 pm

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?

June 22, 2009 pm30 6:02 pm 6:02 pm

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?

June 22, 2009 pm30 6:14 pm 6:14 pm

How come #1 was not (1) .89 hour ?

June 22, 2009 pm30 7:03 pm 7:03 pm

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!

June 22, 2009 pm30 7:09 pm 7:09 pm

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

June 23, 2009 pm30 6:32 pm 6:32 pm

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 :)

June 22, 2009 pm30 10:05 pm 10:05 pm

that’s what I put too but i guess it’s wrong

June 23, 2009 am30 12:37 am 12:37 am

#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.

June 24, 2009 am30 10:01 am 10:01 am

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)

• June 24, 2009 pm30 9:02 pm 9:02 pm

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…

June 23, 2009 pm30 12:15 pm 12:15 pm

how do u do #27 i got 50.4 x 10^6

• June 23, 2009 pm30 8:14 pm 8:14 pm

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.

June 24, 2009 pm30 7:54 pm 7:54 pm

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.

THANKS JD

August 12, 2009 am31 10:49 am 10:49 am

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)

August 12, 2009 pm31 2:20 pm 2:20 pm

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

148. June 3, 2010 am30 8:35 am 8:35 am

yo question 2’s answer is should be number -1 and – 6 not 1 and 6 am i incorrect??

June 3, 2010 pm30 8:03 pm 8:03 pm

oh hiya

June 3, 2010 pm30 8:04 pm 8:04 pm

haha usuk

June 13, 2010 pm30 4:12 pm 4:12 pm

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

June 17, 2010 pm30 2:56 pm 2:56 pm

Don’t you only have to get fifteen of the multiple choice questions right to pass
