Question

Given the constraints, find the vertices of the feasible region and the maximum value of the function:
f(x,y)=x-y
x + 2y < 6
2x - y < 7
x > -2
y > -3
What is the maximum?

Answer 1

we need to figure out the vertices from the inequalities there

Answer 2

so i would graph the inequalities first

Answer 3

i got it now . can u help me with another question tho

Answer 4

Which ordered triple is a solution of the following linear system?:

3n = -18
3m - 2n + 4p = 12
2m - 4n = 16

Answer 5

ok you can find n first from the first equation
once you find n from that equation
you find m from the equation 2m-4n=16

Answer 6

so 3n=-18
what is n?
