Please explain why you got the answer.

9 (LP). Refer to the below graphical solution where W and S are constants and dash lines indicate the (potential) objective function. Note that all dash lines are parallel to each other. Statements: I) If point C is the optimal solution, the B objective function can be min Z=40x + 50x2 II) If point E is the optimal solution, the objective function can be max Z=40x + 4X +3X=W 50x2 X,+2X=S III) 8x1 + 6x2 16 can be one of the constraints. D V) To solve for point C, one can set 8x1 + 6x2 =2W and 3x1 + 6x2 =3S A X A) All statements are incorrect B) Only I), III), IV) are incorrect C) Only II), V) are incorrect. D) Only V) is incorrect 10 (LP). Look at the following Excel spreadsheet. To produce product A and B, each requires process 1 (procl) and process 2 (proc2). E B D cost B 6 3 9 usage 8 10 5 o on 1 2 proci 3 proc2 4 profit 5 A 6 B 7 profit 8 cost Statements I) Cells B5 and B6 can be decision variables II) Cell B7=B2*B5+B3*B6 can be an objective function III) Cells E2 and E3 can be decision variables IV) Cell B8=E2D2+E3*D3 can be an objective function A) Only statement I is correct B) Only statements I and IV are correct C) Only statements I, III, and IV are correct D) All four statements are correct
