$f(x) = 5(x - 5)$
$g(x) = -2(x + 6)$
find $f(-7) + 6$

Explanation:

Step1: Substitute x = -7 into f(x)

We have the function \( f(x) = 5(x - 5) \). To find \( f(-7) \), we substitute \( x = -7 \) into the function. So we get \( f(-7)=5(-7 - 5) \).

Step2: Simplify the expression inside the parentheses

First, calculate the value inside the parentheses: \( -7 - 5=-12 \). Then the expression becomes \( f(-7)=5\times(-12) \).

Step3: Calculate the value of f(-7)

Calculate \( 5\times(-12)=-60 \), so \( f(-7) = - 60 \).

Step4: Calculate f(-7)+6

Now we need to find \( f(-7)+6 \), substitute \( f(-7)=-60 \) into it, we get \( -60 + 6=-54 \).

Answer:

\(-54\)
