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

Does this graph represent a function? Why or why not?
vlabodo [156]

Answer:

A

Step-by-step explanation:

In order for a graph to be a function, it has to only cross the vertical (up and down) lines that it covers once. Since this is an angle, it crosses all the lines in two different places, and isn't a function.
