Question 64969: Solve the system of inequalities by graphing.
y>x
2x+y
2. graph:5x+3y greater than or equal to 15
x is less than or equal to y
x is less than or equal to 4
3. find the max. and min. values and where they occur for z=4x+7y subject to the constraints:
x+y is greater than or equal to 2
3x-4y is less than or equal to 6
6y is less than or equal to x+12
Answer by checkley71(8403)   (Show Source):
You can put this solution on YOUR website! Y>X & 2X+Y<-3
 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y>x and 2x+y<-3).
______________________________________________________________________
5x+3y>=15 & x<=y & x<=4
 (graph 300x200 pixels, x from -6 to 5, y from -30 to 30, of THREE functions 5x+3y>=15, x<=y, x<=4).
_______________________________________________________________________
4x+7y, x+y>=2, 3x-4y<=6, 6y<=x+12
 (graph 300x200 pixels, x from -20 to 20, y from -10 to 10, of FOUR functions 4x+7y, x+y>=2, 3x-4y<=6, 6y<=x+12).
