Question

Please oh please help me with this one! Graph the feasible set for the system of inequalities

x+2y>= 6
x+y>=5
x>=1

Answer 1

?

Answer 2

this should help
eqn 3 x>=1 draw the line and shade to the right
eqn 2 when x = 1 y= 4 y = 5 - x find the section y>5-x; x = 2 y = 3 ;x = 0 y=5
when y = 0 x = 5
eqn 1 when x = 0 y =6/2=3 ; x = 1 y = (6-1)/2 =5/2 when y = 0 x =6

plot the points draw the lines and find the overlapping section.

Answer 3

For each equation solve for y and x by using x=0 then solve for y =0 then use substituttion then you will get x and y coordinate for that equation. do each equation this way and draw a line for each one. then for feasibility you test the areas that are not on the line to see if that number holds true for each equation.
