Can you show us what you have tried (preferably a graph picture)?
1)On your own paper graph the following inequalities. Find the coordinates of the vertices of the feasible region and the maximum and minimum values for the given function. What is the maximum value?
x < 6
y < 2x + 1
f(x,y)= x + y
2)The origin is contained in the solution set of:
y> 2/3 x + 4
y < 1/2x + 1
3)The origin is contained in the solution set for this system of inequalities:
y< 2x + 4
y> -2x - 2
