Question

ALGEBRA 2 HELP THIS GIRL PLEASE:.(
Constraints!
x>0
y>0
-x+3>y
y<1/3-x+1

objective formula: C=5x-4y

Answer 1

Just plot them on an xy plane

Answer 2

I need to know how to like solve it. Or habe someone walk me through it @Hero

Answer 3

1. Plot each inequality as lines on an xy plane. For example instead of x > 0, plot x = 0.
2. Write down the intersection points.
3. Plug the intersection points into the Objective Function

Answer 4

@Hero wait hold on since your talking about graphing

Answer 5

@Hero would what your talking about be easier with that?!

Answer 6

Graphing is always the easiest way.

Answer 7

@Hero well can you help me with the one i just posted?

Answer 8

What is preventing you from figuring it out? Where's your graphing calc?

Answer 9

5x + y = 11
2x - y = 10
______________
7x = 21
x = 21/7
x = 3
y = -4

(x,y) = (3,-4)

Answer 10

You at least know now that the intersection point is (3,-4). To figure out which graph it is, just create a table of x|y values or use wolframalpha
