Use the expression below to answer the question (8-3)^2 / 5 + 2^3 *7. Which is a correct first step? *

25 / 61

Step-by-step explanation:

Given:

(8-3)² / [5 + 2³ × 7]

Computation:

(8-3)² / [5 + 2³ × 7]

(5)² / [5 + 8 × 7]

25 / [5 + 56]

25 / 61

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
