the graph shows the cost of renting snowshoes. Kyle rents a pair of snowshoes at 8 A. M. How much will he pay if he returns them by 2 P. M? How much will he pay if he returns them at 2.15 P. M?​

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
