Homework Statement
<= means less than or equal to.
30 <= X <= 80
10 <= Y <= 30
X + Y <= 80
2. The attempt at a solution
I think I have an idea of how to do it, but I just want to be sure.
Can someone tell me if this is right?
For X, subtract 30 from both sides, leaving X<=50.
For Y, subtract 10 from both sides, leaving Y<=20.
So X(50)+Y(20)<=80
70<=80.
When I subtract from both sides, I just forget about that one inequality?
I also need to graph the Constraints and find the region of feasible solutions as well as all the corner points. I am also lost here. I think I got the graph down, but I'm lost on the corner points. I think I found 2 corner points, but that's it. (30,10) and (30,30).
If you guys could help me out a little here that would be great!
Thanks!
