The graph of the quadratic function y = h (x)in the xy plane is a parabola containing the points (9,8) and (-5,8). Which of the following points could be the vertex of the parabola.

36.5/w

Step-by-step explanation:

Eleanor uses 36.5 feet of wood to build the shelves. Since each shelf is w feet long, the number of shelves Eleanor can build can be found by dividing the amount of wood she uses, 36.5 feet, by the length of each shelf, w.

So, the expression that can be used to find the number of shelves Eleanor builds from the wood is shown below.
