Best ResponseYou've already chosen the best response.0What point in the feasible region minimizes the objective function? X > 0 y>0 y<4 Y < x +5 Above are the constraints Objective Function: C= 9x+y The answer is (5,0) but I don't understand how to get it.

Best ResponseYou've already chosen the best response.0Cause have another example of a problem like that.. & that doesn't work Graph the system of constraints and find the value of x and y that minimize the objective function. 20. Constraints x ≥ 0 y ≥ 0 y ≤ 3 y < − 2x + 5 Ï Ì Ó Objective function: C = −8x + 5y
