Hello!

Answer:

[tex]\huge\boxed{f(-5) = 15}[/tex]

f(x) = 5x + 40

x = -5

Substitute the value of "x" into the equation:

f(-5) = 5(-5) + 40

Simplify:

f(-5) = -25 + 40

f(-5) = 15.

answer:

f(x)=15

reason:
when x=-5 that makes the equation f(x)=5(-5)+40
using order of operations you multiply 5 x -5 first to get -25
add 40 to -25 to get 15
this makes f(x)=15
