For the following linear programming problem, a new variable xa has been added to the problem. If the coefficient of such a variable in the objective and the first and second constraints are 6, 1 and 4, respectively, then the objective value for the optimal solution will: Max Z= x; -3x, +2.x, 2x + 2x - 2x 56 -->> + 2x, 54 X1, X, and xz 20 a Undefined b. Decrease c. Increase d. Remain the same e Unbounded Clear my choice Solving the following linear program graphically, the optimal point is: Minimize Z=3 x1 + 2 x2, subject to 2 x1 + x2 > 10 -3 X1 + 2 x2 s 6 1 xi + 1x2 = 6 X120, X2 20. O a. (5.33, 0.67) b. Infeasible c. Unbounded d.(0,0) e.(4,2) Clear my choice
