I know that but when I plug the problem into it I don't get the correct answer. What am I doing wrong. Can you please explain how to do it to me

Okay. So now do we have to plug in the other points that it passes through

Then do I add 4 to the 7 ?

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.2
No, because you want to solve for a. SO add the 7 to the 4

What 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.

I was thinking you had to plug some stuff in to get the final answer

I used my graphing calc. I graphed y=x+5

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.2
the x intercept of that is (5,0)

That's the vertex.. right

Cause 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

(5,0) is the vertex because y=x+5 is a line

please ignore those random letters the answer is (5 / 2,0)

If you graph, y=2x+5, your x intercept is (5/2, 0)
