Question 1176645
<font face="Times New Roman" size="+2">


On the same set of axes, graph all four of the constraint inequalities.  However, I recommend that you graph them by using the opposite sense, that is if the inequality is "less than or equal", graph "greater than" instead.  That way, instead of the feasible area being where all four solution sets overlap which is sometimes hard to see, what you will have is a feasibility area that is completely clear of shading and is easy to discern.


Once you have the feasibility area defined, check the value of the objective function at each of the vertices to determine which one maximizes the objective and therefore is the solution to the problem.
