Q = 5 x + 3 y and the following constraints: 3 y + 6 ≥ 5 x y ≤ 3 4 x ≥ 8
a. Maximize and minimize the equation Q = 5 x + 3 y
b. Suppose the equation Q = 5 x + 3 y was changed to Q = − 5 x − 3 y , describe how the maximum and minimum would change in the new equation compared to the original equation and explain why you think it is that way.
