3. The number of gallons of water in a tank, y, over a period of x hours is shown in the graph below. 90 80 40 60 50 40 30 20 10 1 2 3 4 5 6 What is the constant of proportionality in this situation? what is the answr DC

perimeter of the base times height

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
