Problems:
1. Consider the simplex tableau
x y u v w M
1 0 3 0 0 0 10
0 0 1 0 1 0 0
0 1 -6 0 0 0 3
0 0 8 1 0 0 7
0 0 5 0 0 1 4
2. The tableau above is the final one in a problem to minimize -x + 2y. The minimum value of -x + 2y occurs when:
- x = 10, y =3
- x = -10, y= -3
- x = 10, y =0
- x = -20, y= 6.
- None of the above
