Mr. Warren is planting two new trees this year. When purchased, the first tree is initially 3 feet tall and grows at a rate of 15 inches per year, and the second tree is 4 feet tall and grows at a rate of 10 inches per year. After how many years will Mr. Warren's trees be the same height?

2.4 years

equal height is 72 inches

Step-by-step explanation:

initial height of tree one = 36inches

initial height of tree two = 48inches

36 + 15x = 48 + 10x

15x = 12 + 10x

5x = 12

x = 2.4 years

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 : )
