Question

Which is the maximum value for the vertices for the following:
y≤2x−3y≤−13x+4
x≤9
f( x,y )=3x−2y
Help?

Answer 1

is that:
y≤2x
−3y≤−13x+4
x≤9

separately?

Answer 2

is x and y greater than zero also? like a standard condition or are u just given x≤9?

Answer 3

I was just givin the x≤9

Answer 4

y≤2x-3
y≤−1/3x+4
sorry wrote it wrong

Answer 5

alright

Answer 6

i would first graph all three lines together on the same graph but graph them as
y=2x-3
y=−x/3+4
x=9

Answer 7

follow?

Answer 8

following
