Step-by-step explanation:

5.20x + 172.90 = 800

          -172.90    -172.90

5.20x = 627.1

/5.20     /5.20

x = 120.5961 or 120.60

5.20 x 120.60 = 672.12

172.90 + 627.1 = 800

the answer is 121

36 is the final answer! : )

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.   .
