Each table represents a proportional relationship. For each, find the constant of proportionality and write an equation that represents the relationship

Aswimming pool is a rectangle with semicircles on the end. the rectangle is 12 meters wide and 30 meters long. the diameter and width of the swimming pool are equal. sketch and label an overhead diagram of the swimming pool. find the area of the swimming pool floor.

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
