A tub is full of water. Water is draining from the tub at a constant rate measured in gallons per minute. The volume, V, of the water in the tub can be described by the
equation V = 14 – 7/2t, where t is the time in minutes. Which statement is correct?

the answer is 288..

hope this

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
