lch is 23 - Question 5. After solving a Phase 1 LP with the simplex method, the following special form of the equations is obtained 12 을 + 141 143 + 443 305 을 111 7x4 + fx6 + tur y2 + 493 and the following special form of the objective, 0+ yı + y2 + 43, where yi, y2 and 43 are the artificial variables. (Note: the Phase I LP was solved as a mini- mization problem; it was not transformed to an equivalent maximization problem.] In answering the questions below, do not attempt to solve the LP. 1. If the original LP is feasible, (a) state the initial basis for Phase 2, (b) state the corresponding basic feasible solution for the original LP, and (c) determine the special form of the objective for the initial Phase 2 basis, where the original LP has objective maximize z = 21 - 222 +223. 2. Circle the most appropriate answer. Is the original LP (a) infeasible (b) unbounded (c) optimal (d) unbounded or optimal?
