Define a variable and write each phrase as an algebraic expression
10. 15 jumps less than kelsy
11. 9 times the amount of doughnuts purchesed
12. 23 dollars more than what elaina earned

b.an increase in a causes b to decrease

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 : )
