Given the following the LP:
Min Z=2x_1+3x_2
st. 2x_1+ x_2≥16 (1)
x_1+?3x?_2≤36 (2)
x_1+ x_2≥10 (3)
x_1 ≤18 (4)
x_1+ 2x_2≤ 5 (5)
x_1 ≥ 0 (6)
x_2 ≥ 0 (7)
a) Draw the feasible region of this LP on a graph. Express the feasible region by its extreme points. (Give a letter name to all points on the graph.)
b) Which constraint/(s) are redundant and why?
c) What is the optimal solution? Express it as (x_1,x_2 )=z^*. Show the optimal point the graph.
d) Indicate all of the corner point solutions and their feasibility or infeasibility. For feasible points, write down the objective functions. (Need a ?table as follows. You are going to decide how many points will be written on the table.)
