@jdoe0001 @Compassionate can any of you please help me?

OpenStudy (compassionate):

@Directrix is good with Directrix's. Lol.

OpenStudy (anonymous):

ohh k @Compassionate can you check the others?

OpenStudy (anonymous):

and please correct me if im wrong I would really appreciate it

OpenStudy (compassionate):

Lets start with question 10. \[\frac{ y^2 + 7y + 12 }{y^2 - 2y - 15}\] Now this one is easy. Just factor both the numerator and the denominator. Do that for me real fast. (Hint: they go in binomials)

OpenStudy (anonymous):

k

OpenStudy (compassionate):

So show me once you factored it.

OpenStudy (anonymous):

y+4/y-5 c?

OpenStudy (anonymous):

@Compassionate ?

OpenStudy (compassionate):

\[\frac{ (y+3)(y+2) }{(y + 3)(y -3) } = \frac{ y + 2 }{ y - 3 }\]

OpenStudy (anonymous):

thats not an answer choice

OpenStudy (compassionate):

\[\frac{ (y+4)(y+3) }{ (y+3)(y-5) } = \frac{ y+4 }{ y-5}\] So yes, you are correct. 10. = c.

OpenStudy (anonymous):

k 9?

OpenStudy (compassionate):

Lets do problem 4. \[(3x^2 - x^2 -x -1)\div x-1\] Factor the left side.

OpenStudy (anonymous):

k

OpenStudy (anonymous):

(x-1)(2x+1)

OpenStudy (anonymous):

@Compassionate

OpenStudy (compassionate):

No\[(x - 1)(3x^2 + 2x + 1) \div (x - 1)\] Now cancel out x - 1. .

OpenStudy (anonymous):

so 2x+1

OpenStudy (compassionate):

No. \[3x^2 + 2x + 1\] C.

OpenStudy (anonymous):

ohh k whats next?

OpenStudy (anonymous):

IS 5 b 12?

OpenStudy (compassionate):

I can tell you 9. is wrong. The equation doesn't even have cubes. So it's either A or D.

OpenStudy (anonymous):

@Compassionate what about the rest?

OpenStudy (compassionate):

You never responded to my last post. We're still solving 9.

OpenStudy (anonymous):

ohh for ( i pick d because the squared

OpenStudy (anonymous):

am i corretc ?

OpenStudy (compassionate):

Yes. That's all I can help with. I don't know how to do the rest. @Mertsj might be able to assist you with some. But these are a lot of question and cover a broad range of mathematics.

OpenStudy (anonymous):

@Compassionate i have 5 that u might now what to check em ?

OpenStudy (anonymous):

OpenStudy (compassionate):

For the first one, factor all the factor able terms then cross cancel.

OpenStudy (anonymous):

k give me a min

OpenStudy (anonymous):

is it d?

OpenStudy (anonymous):

is 12 correct

OpenStudy (compassionate):

Yes.

OpenStudy (anonymous):

is 11 d?

OpenStudy (compassionate):

Yes

OpenStudy (anonymous):

okay 13?

OpenStudy (mertsj):

number 3 is C

OpenStudy (anonymous):

#3 part 1 or 2?

OpenStudy (compassionate):

For 13. invert the denominator to the reciprocal and cancel.

OpenStudy (mertsj):

Number 4 is C

OpenStudy (anonymous):

@Compassionate 13 is c ?

OpenStudy (mertsj):

Number 5 is 96

OpenStudy (mertsj):

Number 6 is correct.

OpenStudy (compassionate):

13 is c, yes.

OpenStudy (mertsj):

Number 7 is B

OpenStudy (anonymous):

@Compassionate 14?

OpenStudy (anonymous):

@Mertsj #8 is d correct?

OpenStudy (mertsj):

Number 8 is D

OpenStudy (anonymous):

#9 d correct @Mertsj ?

OpenStudy (mertsj):

Number 10 is C

OpenStudy (mertsj):

Number 9 is D

OpenStudy (anonymous):

@Mertsj #14 and 15 and im done

OpenStudy (anonymous):

@Compassionate can u guide me in 14 and 15?

OpenStudy (anonymous):

or @Mertsj I would appreciate it :)

OpenStudy (mertsj):

Number 14 is D

OpenStudy (anonymous):

btw is 13 c ?

OpenStudy (mertsj):

15 is D

OpenStudy (mertsj):

What test is this?

OpenStudy (anonymous):

its a pre test i had to take before taking the test i tried my best with the answers i had

OpenStudy (anonymous):

13 is c corretc?

OpenStudy (mertsj):

no

OpenStudy (anonymous):

ohh the whats 13?

OpenStudy (mertsj):

Ok. So if this is a pretest and I have done 11 of 15 problems for you, how does that help you?

OpenStudy (anonymous):

no i have more than 15 i had 45 i did the other this is just the ones i didn't get

OpenStudy (anonymous):

it helps me with my mistakes so i know that im doing the procedure correctly this is helping me prepare for my test that is on monday :)

OpenStudy (mertsj):

13 is A

OpenStudy (anonymous):

okay tahnks :)@Mertsj
