Answer:

7

Step-by-step explanation:

An<em> "additive inverse"</em> refers to a number that when added to a specific number equals to <em>"zero."</em>

In the question above, the additive inverse of -7 is 7 because:<u> -7 + 7 = 0</u>

Other examples:

1. The additive inverse of 2 is -2 because: 2 + (-2) = 0

2. The additive inverse of -100 is 100 because: -100 + 100 = 0

3. The additive inverse of \frac{1}{2} is -\frac{1}{2} because: \frac{1}{2} + -\frac{1}{2} = 0
