20 points and brainliest determine f(5) for f(x) = 1/3 (5 - 4x). 5 - 55/3 -5 25/3

To solve this equation we must first plug in 5 for x.

 (5 - 4x)
               ↓ 
(5 - 4 · 5)

The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

(5 - 4 · 5)

(5 - 20)

The next step would be to subtract both of the numbers within the parenthesis.

(-15)

Now we must multiply.

-  · 15 =  - 

- 

Now we simplify our answer to get our final answer.

-5
