To evaluate the expression \(-4 - (-9)\), we can use the concept of the additive inverse. The additive inverse of a number is what you add to that number to get zero. In this case, we want to simplify the expression \(-4 - (-9)\).
To simplify, we know that subtracting a negative number is the same as adding its positive. Therefore:
\[ -4 - (-9) = -4 + 9 \]
Now we can compute:
\[ -4 + 9 = 5 \]
So, the equivalent expression \(-4 + 9\) evaluates to \(5\).
Based on the responses provided, the correct option is:
Because \(-4 + 9\) is an equivalent expression, the answer is 5.
