Answer: -74

Step-by-step explanation:

First you have to solve - 2y - 9 = 7 to find what "y" equals so we can plug that into 9y - 2

1. Solve -2y - 9 =7:

-2y = 16

y = -8

2. Plug -8 into the expression 9y - 2:

9(-8) - 2

-72 -2

-74!

Im sorry if i didnt do this correctly :/

It’s algebra it says find each function value here is a picture of the work sheet

s344n2d4d5 [400]

8 > 1 so: a(x) = -4x + 7

a(8) = - 4(8) + 7 = - 32 + 7 = - 25

-6 ≤ 1 ≤ 1 so: a(x) = 2x - x²

a(1) = 2(1) - (1)² = 2 - 1 = 1

-7 ≤ -6 so: a(x) = |x - 8|

a(-7) = |-7 - 8| = |-15| = 15

-6 ≤ -3 ≤ 1 so: a(x) = 2x - x²

a(-3) = 2(-3) - (-3)² = -6 - 9 = - 15

-6 ≤ -¹/₂ ≤ 1 so: a(x) = 2x - x²

a(-¹/₂) = 2(-¹/₂) - (-¹/₂)² = - 1 - ¹/₄ = - 1¹/₄

⁹/₄ > 1 so: a(x) = -4x + 7

a(⁹/₄) = - 4(⁹/₄) + 7 = - 9 + 7 = - 2
