Answer and show me the work. solve for x

1. The two marked angles are supplementary, so their sum is 180°.

... (15 +5x) + (14x -6) = 180

... 19x + 9 = 180 . . . . . . collect terms

... 19x = 171 . . . . . . . . . . subtract 9

... x = 9 . . . . . . . . . . . . . divide by 19

2. The two marked angles are corresponding angles, so are congruent.

... 13x -7 = 11x +11

... 2x -7 = 11 . . . . . . . subtract 11x

... 2x = 18 . . . . . . . . add 7

... x = 9 . . . . . . . . . . divide by 2

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
