Graph the functions y = -x + 51 + 2 and y = -(x - 1)2 + 3. Which statement is true?
The functions have one point of intersection.
The function y = -x + 5 + 2 has the greater y-intercept.
The function y = -(x - 1)2 + 3 has the greater maximum.
The functions are both decreasing over the interval (-2,-5).

your question is wrong. What does 51+2 mean

Step-by-step explanation:

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.
