Find the minimum and maximum values of k=-x +3y subject to the constraints. 2x -y> 4 -x+2y< 4 y< 6 x> 0, y> 0
note: the question accompanies a graph too.

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
