Question

Evaluate the function f or f(-9) if f(x) = 3/5x +8Help please​

Answer 1

Answer:

f(-9)=2.6

Step-by-step explanation:

Plug in -9 for x

f(-9)=3/5(-9)+8

Combine like terms

f(-9)=-5.4+8

f(-9)=2.6

Answer 2

Answer:

F(-9) would be 13/5

Step-by-step explanation:

1.) add -9 into the equation as the subsitute for x

(should look like $\frac{3}{5} (-9)+8$ )

2.) Solve the equation with basic algebra

(should look like $\frac{-27}{5} +8\\\frac{-27}{5} +\frac{40}{5} =\frac{13}{5}$
