Using the following image, apply what you have learned about linear pairs and solve for x.

Step-by-step explanation:

Linear pair, so sum of both angles is  180

x - 2 + 2 +4x = 180

Add the like terms

5x +0 = 180

5x = 180

Divide both sides by 5

x = 180/5

x = 36

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
