Answer 8

Answer 9

Answer 11

"Like terms" means that all the x-values go with the x-values and all the y-values go with the y-values

Answer 12

First you should put the values that are like together. So for example,

6x+4+7x should be 6x+7x+4 -- they need to be re-arranged. Can you rearrange the terms in your question like that for me?

Answer 13

i think it may be a or d

Answer 14

We'll get there, let me walk you through it okay? :) Please rearrange the terms like I demonstrated

Answer 15

y2+13x+3y−1

Answer 16

is that what @funnyguy2 just did correct?

Answer 17

b

Answer 18

@funnyguy2, just giving the answer doesn't help this person, and in math if people take shortcuts early on while the math is easy they're completely confused later. Please don't do it.

Answer 19

but is he right? @kohai

Answer 20

use this
http://www.mathpapa.com/algebra-calculator.html

Answer 21

@kohai can you try this ^^^^

Answer 22

No. He isn't. That's a +1 not a -1.

Answer 23

-1

Answer 24

No, because I'm in calculus and I don't need a calculator to do algebra.

Answer 25

so would it be d?

Answer 26

Oh. Sorry. The answer choices are laid out weird, I was looking at C. B is correct. In the future please do not take short cuts in math.

Answer 27

can you guys help me with a few more please? @kohai @funnyguy2

Answer 28

Yeah. I could. But funnyguy is just going to give you the answer anyways.

Answer 29

Answer 30

@kohai two calculators say -1

Answer 31

7x + 3y – 2 + 6x + 1 + y^2

That's a +1 right there.

Answer 32

I was looking at it right -- it's D, not B

Answer 33

anyone prove me right

Answer 34

OH. I know why it says -1. I completely missed the -2 there. Sorry. You were right.

Answer 40

Right or wrong, direct answer's don't deserve medals.

Yeah you can give the kid all the answers, I'm not going to be part of that

Answer 42

i'm not allowed to help you on a test

Answer 43

I was wrong. I didn't see a number. The kid was right.

Answer 45

Answer 47

Everyone makes mistakes, @kohai can fix that. Please stop giving direct answers, anyhow.

Answer 53

@funnyguy2
Your not allowed to help on a test, correct. Your not allowed to give direct answers, either.

it comes on windows

Answer 56

i promise this is not a test

Answer 57

Stop interrogating the asker and give hints/clues to his/her problem. Just not the answer. At least they will LEARN something..

Answer 58

attach the worksheet here

Answer 59

My new favorite person @dtan5457

Answer 60

Generally people who are new 1) Don't know that they can't have test help 2) Put the amount of points the question is worth and 3) Flat out admit that it's a test.

I seriously doubt this kid is taking a test right now.

Answer 61

If it's from k12 it's a test @kohai

Answer 62

This might be shocking, but they DO give homework assignments in k12. I know, I was in k12.

Answer 63

homework assignments don't start with
http://static.k12.com/

Answer 64

@kohai
Feel free to help the asker, as I have to go. Direct answers pisses me off more than it should, but that's probably because it's been dozens of times where I'm giving page long explanations, and some kid ruins my 15 minute lesson with the letter of the answer.

As for @funnyguy2
I don't know why your so concerned wheather it's a test or not. Even if it was, you violated as many rules as he did. Just explain the question WITHOUT the answer, and move on.

Answer 65

i'm in k12

Answer 66

im attaching it now. one sec

Answer 67

That's what annoyed me too @dtan5457.

Answer 68

You know as well as I do that if a kid don't understand algebra 1 because someone just gives an answer and that's all they want, they'll be lost algebra 2 and onward.

Answer 69

i'm waiting

Answer 70

my teacher emailed me this to practice.

Answer 71

this questions not on there

Answer 72

@kohai @funnyguy2

Answer 73

i didnt send that page

Answer 74

God will you just give it a rest? Seriously, why are you continuously attacking this kid? Find someone who is clearly cheating to accuse of cheating.

Answer 75

@barbydewy just close this question and post another if you need help. This guy isn't doing you any good.

Answer 76

its a she and thank you @kohai

Answer 77

Not in my experience. As I said, cheaters who are new 1) Don't know it's cheating to get help on tests 2) Post the amount of points it's worth and 3) Blatantly say it's for a test if you ask. The kid isn't cheating.

Answer 78

she is clearly cheating

Answer 79

Just leave. Seriously. You're just making yourself look stupid.

Answer 80

i have 3 titles

Answer 81

Yeah? I'm 20 points higher on the smart score, and I have over 3 titles.

Answer 82

@kohai im trying to send u a message but its saying i cant what do i do

Answer 83

@dan815

Answer 86

Answer 87

Answer 88

Answer 89

Answer 90

@funnyguy2 You must not know what cheating is, I've read through everything - she's not cheating, please stop being delusional.

Answer 91

thank you @Jesstho.-.

Answer 92

Wow, I just read through it all, she is not cheating, kohai is right on what newcomers typically do on test questions. The attachment obviously says math semester assessment prep, so don't attack her any more.
