Answer:
the second one I can't give a explanation cause my wrist is broken so it's harder to type hope this helps
Assuming that the pool was drained at a constant rate, the speed at which it was drained can be expressed as a function of time. In this case, the pool level will be expressed in feet per hour.
The time changed by 4 hours (6-2), and the level of the pool changed by -8 feet (2-10). Diving the feet by the hours to get the rate of decreasing depth, we find that the rate equals -2 feet/hour.
-9x=-36
divide both sides by -9
to get x by itself
to get +x
-9x/-9= -36/-9
cross out -9 and -9, then becomes -1*-1*x= x
x= -36/-9
answer:
x= 4
