WebJul 29, 2024 · 3 Answers Sorted by: 2 If you solve the problem graphically you should solve the objective function Z for x 2 as well. Z = 500 x 1 + 300 x 2 Z − 500 x 1 = 300 x 2 Z 300 − 5 3 x 1 = x 2 Now you set the level equal to zero, which means that z = 0 and draw the line. This line goes through the origin and has a slope of − 5 3. Web3) Infeasibility in a linear programming problem occurs when A)there is an infinite solution. B)a constraint is redundant. C)more than one solution is optimal. D)the feasible region is …

WebThe two important theorems of the objective function of a linear programming problem are as follows. Theorem 1: Let there exist R the feasible region (convex polygon) for a linear programming problem and let Z = ax + by be the objective function. When Z has an optimal value (maximum or minimum), where the variables x and y are subject to … WebTo conclude x3=1 is the best we can do, and the new solution is x1=2,x2=0,x3=1,x4=0,x5=1,x6=0 (9.12) and the value of z increases from 12.5 to 13. As stated, we try to obtain a better solution but also a system of linear equations associated to (9.12). In this new system, the (strictly) positive variables x2,x4,x6have to appear on the … commonwealth attorney virginia prince william
