Step-by-step explanation:
this is the only point that is in the overlapped shading area
To find the volume of a square-based pyramid, use the formula V = A(h/3), where V is the volume and A is the area of the base.
Okay, so we have 20x+5y=-15.
To find y, let's plug in 0 for x, that way we have 20(0)+5y=-15.
Now do 20(0) and we have the equation: 5y=-15
divide both sides by 5 and we get y=-3!
