b. 7x^2 − y

C. 7x − y

d. -7x^2 − y

Answer 1

Additive inverse of something is what when added to the something give 0 as a result. That is all you need to know.

Example

3
additive inverse is -3 since
3 + (-3) = 0

Answer 2

so its A?

Answer 3

Test to see if you are right:
-7x^2 + y + (7x^2 + y) = 2y
But that is not zero. So, no.

Answer 4

no..try otther option ...

Answer 5

oh its B xD right?

Answer 6

math is a subject that can be learn by practice not by just selecting...

Answer 7

but im pretty sure its B ./..

Answer 8

but i just want to be sure.

Answer 9

if you put D then see it..
-7x^2-7x^2+y=-14x^2+y

Answer 10

yuppp..its B...try it here..!!!

Answer 11

Test to see if you are right
-7x^2 + y +(7x^2 − y) = 0
So, yes.

Answer 12

thanks ;d
