Find the volume of the described solid. The solid lies between planes perpendicular to the x-axis at x = 0 and x=7. The cross
sections perpendicular to the x-axis between these planes are squares whose bases
run from the parabola v=-5sqrtrootx to the parabola y=5 sqrt x

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

answer: 12

step-by-step explanation:

because yes
