Use graphical methods to solve the linear programming problem.

1) Maximize z = 6x + 7y

Subject to:

2x + 3y 12

2x + y 8

x 0, y 0

Use the Venn diagram to find the requested set.

2) Find A B.

Let U = {q, r, s, t, u, v, w, x, y, z}

A = {q, s, u, w, y}

B = {q, s, y, z}

C = {v, w, x, y, z}

Determine the following.

3) (A' C) B'

Use a Venn Diagram and the given information to determine the number of elements in the indicated region.
