Question
Solve each linear programming problem.$$\text { Maximize } z=2 x+y \quad \text { subject to } \quad x \geq 0, \quad y \geq 0, \quad x+y \leq 6, \quad x+y \geq 1$$
Step 1
The constraints are $x \geq 0$, $y \geq 0$, $x+y \leq 6$, and $x+y \geq 1$. The first two constraints mean that we are only considering the first quadrant. The other two constraints are lines in the xy-plane. Show more…
