What is the value of x?

Step-by-step explanation:

since we can see that the lines are parallel

and we can see that the both are interior angles and when we sum up both angles we get 180

2x - 5  + 45 = 180

2x  + 40 =180

2x = 180 - 40

2x =140

x = 140/2

x = 70

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
