Question

answer about the following linear program: max -5x+y subject to (A)-2x+0.8y<=4 (B)5x+2y>=10 (C)x+2y>=3 (D)x>=0 (E)y>=0 Questions: 1. Draw the lines that define the boundary of feasible region, and shade the feasible region, is the feasible region bounded or not bounded? 2.Determine the optimal solution and its value 3.Is the optimal value to the linear program bounded or unbounded? 4.Determine what constraints are binding the optimal solution? 5.suppose we add the constraint y<=3 to our linear program (A-E), determine the new optimal solution and its value 6. suppose we add the constraint x<=1 to our linear program (A-E), determine the new optimal solution and compare it to the the one in Question 2. Did it change? Why?
