Answer:

Step-by-step explanation:

9x - 77 = 7x - 43

9(17) - 77 = 153 - 77 = 76

7(17) - 43 = 119 - 43 = 76

Find AB. i’m literally so dumb i don’t know math

Hatshy [7]

Step-by-step explanation:

AC = AB + BC

25x - 19 = 9x + 7 + 5x + 7

25x - 19 = 14x + 14

25x - 14x = 14 + 19

11x = 33

x = 33/11

x = 3

AB = 9x + 7

= 9(3) + 7

= 27 + 7

= 34

When something is nonlinear it doesn't fit the criteria, on a graph it will be curved, never straight
