Check my work for linear programming questions please! (I'll post my answers+the question in the comments)

Answer 1

Here is the first question. (0,5) DOES yield the maximum profit, but it isn't a valid vertice on the graph, I don't think.

Answer 2

Oops, I mean (5,0) yields the highest profit ^^^

Answer 3

Here is the graph for the question above.

Answer 4

Is this right?

Answer 5

Oops, I just realized a mistake I made... (0,5) IS on the graph. So that must be the answer for that one...

Answer 6

If you graph it on desmos.com, you can visually see where the lines overlap, if you do graph it there, you can use the inequality symbols to actually shade in teh sdies.
