Suppose x and y vary together such that Δ y Δ x = 3 , or Δ y = 3 ⋅ Δ x . This means that there is a constant rate of change of y with respect to x . Furthermore, assume that when x = 4 , y = − 2 . Write a formula that expresses y in terms of x .

The volume, v, of a rectangular prism is determined using the formula, where / is the length, w is the width, and his theheight of the prism. carltren solves for w and writes the equivalent equation w=using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches,and a length of 3.2 inches?
