🗑
Linear programming thereom   The feasible region of every linear programming problem is convex, and the maximum or minimum quanity is determined at one of the vertices of this feasible region.  
🗑
What are vertices?   The intersections of the boundaries are called vertices of a feasible set.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
