The feasible region for a linear programming problem is bounded by x > 0, y = 0, 2x + 3y = 12. Find the location of the maximum and minimum values of f(x, y) = 5y - X.
The maximum value of f(x, y) occurs at Select Choice
The minimum value of f(x, y) occurs at Select Choice

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
