Question

The graph of the feasible region is shown.

f = 6x + 3y
The x y coordinate plane is given. Three lines and a shaded region are on the graph.
  • The line 2x + y = 40 enters the window in the first quadrant, goes down and right, crosses the line x + 5y = 100, crosses the line 8x + 5y = 170, and ends on the positive x-axis.
  • The line 8x + 5y = 170 enters the window on the positive y-axis, goes down and right, crosses the line x + 5y = 100, crosses the line 2x + y = 40, and exits the window in the first quadrant.
  • The line x + 5y = 100 enters on the positive y-axis, goes down and right, crosses the line 8x + 5y = 170, crosses the line 2x + y = 40, and exits the window in the first quadrant.
  • The shaded region is below the three lines, above the x-axis, and right of the y-axis.

Find the corners of the feasible region. (Order your answers from smallest to largest x, then from smallest to largest y.)

(x, y) = 
 
 
 
 
 
 
 
(x, y) = 
 
 
 
 
 
 
 
(x, y) = 
 
 
 
 
 
 
 
(x, y) = 
 
 
 
 
 
 
 
(x, y) = 
 
 
 
 
 
 
 


Find the maximum and minimum of the given objective function (if they exist). (If an answer does not exist, enter DNE.)

maximum     f  =   
minimum     f  =
