Question

I'll give a medal!!

Subtract and simplify:

(−y2 − 3y − 5) − (−3y2 − 7y + 4)

A. 2y2 − 10y + 4
B. 2y2 + 4y − 9
C. −2y2 − 10y − 1
D. 2y2 − 7y − 9

Answer 1

-y^2 - 3y - 5 +3y^2 + 7y - 4

2y^2 + 4y - 9

B

Answer 2

I agree with Link :)

Answer 3

yay

Answer 4

THANK YOU SO MUCH!!

Answer 5

thats what we are here for :)

Answer 6

No problem

Answer 7

I have another question, but I can't type another in, so, I'll put it here.

Subtract and simplify:

(2p2q − 3pq2 + q3) − (p2q + q3)

A p2q − 3pq2+2q3
B p2q − 2pq2
C p2q − 3pq2
D 2p2q − 3pq2

Answer 8

2q2p - 3pq2 + q3 - p2q - q3
2q2p -3qp2 + 2q3

answer a

Answer 9

One more, one more! It's just one, don't worry. :P

Add:

(8x + 2y − 3z − 4) + (−4x − 5y + 4z + 6)

A −4x + 3y − z + 2
B 4x − 3y − z + 2
C −4x + 3y −z ? 2
D 4x − 3y + z + 2

THANKS!

Answer 10

4x - 3y + z + 2
