    DO YOU KNOW HOW TO DO THIS YET? I SAW THAT YOU WERE BEING TOLD TO PLUG IN EARLIER BUT WAS NOT PROPERLY TAUGHT THE CONCEPTS BEHIND THESE THINGS

    I'm not really sure how to do this @Michele_Laino

    I'm sorry, I'm not good with linear programming

    I'm not very good at these. Do you know how to do them?

    i believe linear programming is a graphical boundary setup and examines the vertixes (corners created by intersections)

    try wolframalpha.com it does it and then shows you the steps...

    @amistre64 How do I figure out if it is infeasable, unbounded, an optimal solution, or alternate optimal solutions?

    well, i would graph the constraints ... but im still trying to get a better grasp on what is being asked. |dw:1443898656805:dw|

    (-inf,inf) is one 'corner' (-inf,0) is one 'corner' (1,0) is a corner and (1,2) is a corner but there is usually some function that these constraints can be compared with, it represents a surface that caps the xy plane

    Ok so how do I come to an answer choice?

    i dont know, i could be misreading the info, but it seems incomplete to me. https://www.youtube.com/watch?v=M4K6HYLHREQ

    It is incomplete.

    personally, i think the (-inf,inf) makes it unbounded ... but i cant say for sure since I am many years removed from the definitions

    @roast_master_says Incomplete is not an answer choice. Is it unbounded?

    it should be noted that a region with infinity as a vertex point is not a guarentee that the system is unbounded. for some reason

    THEY'RE ALL DEFINITIONS INFEASIBLE WOULD BE NO 'FEASIBLE' OR POSSIBLE SOLUTION UNBOUNDED WOULD HAVE NO BOUNDS AND COULD EITHER BE NEGATIVE INFINITY OR POSITIVE INFINITY SO, THERE ARE THREE POSSIBLE SOLUTIONS INFEASIBLE UNBOUNDED OPTIMAL (FEASIBLE)

    So it's unbounded??

    UNBOUNDED, LIKE AMISTRE SAID, JUST FOR CLARIFICATION REFERS TO THE UNBOUNDED REGION, BUT DOES NOT REFER TO THE LINEAR PROGRAM BEING UNBOUNDED

    Oh so it's optimal?

    the question where you pluggd in numbers was completely different than this one anywyz i hope you understand th concepts this time.

    How do I figure out if it's infeasible or optimal?
