Select the statements that are true for the graph of y = −(x−0.5)^2+9 1. the graph has a minimum. 2. the graph has a maximum. 3. the vertex is (0.5, 9) . 4. the vertex is (−0.5, 9) i need this done by 1: 30 2/22/2018 you! (:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
