c.) -2x+7
d.) -2x-7

Answer 1

CcccccccccCcccc. Is the answer

Answer 2

Answer:  The correct option is

(A) -2x+7.

Step-by-step explanation:  We are given to find the additive inverse of the following expression :

$E=2x-7.$

We know that

for any a, the additive inverse is given by b if a+b = 0.

Let y be the additive inverse of the given expression E.

Then, we must have

$E+y=0\\\\\Rightarrow 2x-7+y=0\\\\\Rightarrow y=-2x+7.$

Thus, the required additive inverse of the given expression is -2x+7.

Option (A) is CORRECT.
