Question

Find the maximum value

Answer 1

(-2,6) (-4,6) (-4,1) (-2,1)
5x+4y
(-2,6)=-10+24=14
(-4,6)=4
(-4,1)=-16
(-2,1)=-6
14 max

Answer 2

hum, very interesting

ok, so we have 5x+4y

we want x and y to be as big as possible

that means we want to pick the most positive x value and most positive y value

ok, by our bounds, te most positive x value is -2

the most positive y value is 6

so the max value iswhen x=- and y=6

that is C=5(-2)+4(6)

C=-10+24

C=14

the max value is 14
