5. which ordered pair is a solution pf the equation y = -5x + 4 a. (2, 14) b. (5, -29) c. (3, -19) d. (5, -21) 7. -4 = g + 1 a. g = -4 b. g = 4 c. g = -5 d. g = -3 6.

1. Replace x with the given values and see if the equation equals the Y value:

y = -5x +4  

 -5(5)+4 - -25 +4 = -21

The answer is D.

2. -4 = g+1

Subtract 1 from each side:

-5 =g

The answer is C.

3.  The 2nd chart is correct, ( the top one on the picture with 2) because when Tony is 5 the line is on Y = 0, when the line is on 6 it is on Y=1, which keeps Tony at 5 years older.

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.
