Hello NonMathEmatical
These are all very straightforward questions about inequalities and linear programming. Have you tried them? I Googled 'Linear Programming' with the following result. You might find something here to get you started.

Hi I have real difficulties with the following three problems, any help will be appreciated.
Write a system of linear inequality that describes the shaded region:
Determine graphically the solution set for the system of inequality and indicate whether the solution is bounded or unbounded:
Solve the linear programming problem by the method of corners:
Sorry for the poor picture quality but they are made by phone
Thank you all in advance!

Since the region is above the x-axis and to the right of the y-axis, and I see no dotted-lines on the axes, two of the inequalities are
You're given two equations of lines, x + 2y = 8 and 5x + 2y = 20. Both lines are solid, and the shaded region is either to the left or below the lines. The inequality symbol you need for both is less-than-or-equal-to. So the system of inequalities is

Grandad thank you for your replay, I just don't have time to learn everything again but the first video was good.. Starting from there I will try to make something but from now I am sure that it will be an total failure
yeongil thank you very much for your solution and your explanations
Unfortunately, the answer to one homework exercise is not going to help much on the test, when you don't understand the underlying material (and since the questions on the test will be different).
So please make the time to learn how to set up and solve linear programming word problems.
In fact I don’t care about the exams because I have done them already. The previous home-works were with 35-40 problems for solving, I have done them applying the strategy called “google it and you’ll learn how to solve them” but those are incomprehensible for me. Is that so hard to understand?? It’s not laziness or not taking responsibility…!!
PS: Thank you for the link!
