Answer:
15
Step-by-step explanation:
f(x) = 5x + 40
Put x as -5.
f(-5) = 5(-5) + 40
f(-5) = -25 + 40
f(-5) = 15
Answer:
15
Step-by-step explanation:
We already know that [tex]f(x)=5x+40[/tex]. To find [tex]f(x)[/tex] when [tex]x=-5[/tex], we simply need to plug -5 into the equation. Thus:
[tex]f(-5)=5(-5)+40=-25+40=15[/tex]
The answer is 15.
