If the rectangular fish tank below is completely filled with water, and the 900 cubic centimeters are poured out, how high will the water

The high of the water is 2 cm.

Step-by-step explanation:

The equation of this volume is:

We know that the volume is 900 cm³. So we just need to put this value in the above equation and solve it for x, which is the height.

Therefore, the high of the water is 2 cm.

I hope it helps you!

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
