Question

Graph the system of constraints and find the value of x and y that maximize the objective function.
( I will attach a picture. ) *

Objective function: C = 7x – 3y

(2.5, 2.5)
(0, 2)
(0, 0)
(5, 0)

Answer 1

I thought we went over this already

Answer 2

Its different?

Answer 3

It's the same one you posted yesterday.

Answer 4

No , its 4 different constraints now . Yesterday it was 2 .

Answer 5

Nope, it was four yesterday as well

Answer 6

I will double-check the constraints, but I'm pretty sure they are the same.

Answer 7

I just looked, yesterday it was 2 . and graphing them .

Answer 8

Hmm, for some reason the question you posted yesterday vanished.

Answer 9

Yesterday, it was FOUR! I promise

Answer 10

How , did it vanish ? lol . It wasn't 4, this is new stuff today. lol

Answer 11

Because it was four. I saw it with my own eyes and I don't know how the question vanished, but it did.

Answer 12

I don't think so , lol .

Answer 13

Well it has the same solution for sure.

Answer 14

Wouldn't I plug in x1 for x and y1 for y ?

Answer 15

Yes, and if you did, you would notice that the only two points that would work are (2.5,2.5) and (5,0) however, (5,0) produces a greater value for C

Answer 16

Same as yesterday

Answer 17

So , it would look like C = 7(2.5) – 3(2.5) = 10 . . . .?

Answer 18

C = 7(5) - 3(0) = 35

Answer 19

and which ever one has the greatest answer is the answer ?

Answer 20

You still have to make sure the point meets all of the constraints of course. In this case, (2.5, 2.5) and (5,0) both meet all of the constraints, however (5,0) produces the max value.

Answer 21

so (5,0 ) is the answer .

Answer 22

This is the same conclusion you came to on your own yesterday. Remember? How did you forget that fast? You posted this same exact problem yesterday.

Answer 23

I don't know . I have a bad memory. That's why i'm NOT good at math . . . I get confused tooo easy.

Answer 24

I see. I'm sorry to hear that.

Answer 25

Tell me about it . . . :/
