The dimension of a rectangular tank filled with water is 50m × 16m × 60m. At a certain instant, the tank begins to drain. Find the rate at which the volume of water is drained if the depth of water is changing at a rate of 12 m/min.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
