Question

I need help with #19, the points of the graph and which way would be shaded.

B Solve the linear programming problems stated in Problems 17–38.
P = 10x + 75y
x + 8y < 24
17. Махimize
subject to
х, у 2 0
18. Махimize
P = 30x + 12y
subject to
3x + y < 18
х, у 2 0
19. Minimize C = 8x + 9y
subject to 5x + 6y > 60
x, y 2 0
20. Minimize
C = 15x + 25y
subject to
4x + 7y > 28
х, у2 0
P = 5x + 5y
subject to 2x + y< 10
x + 2y < 8
21. Маximize
х, у 2 0
22. Маximize
P = 3x + 2y
subject to 6x + 3y < 24
Зх + бу < 30
х, у 20
23. Minimize and maximize
z = 2x + 3y
subject to 2x + y> 10
x + 2y 2 8
X, y > 0
