Question

Help would be appreciated! Will Medal!
State the minimum and maximum values (if any) of the linear expression under the given constraints:
1. 0<=y<=6-x
0<=x<=4
x+3y

Answer 1

@robtobey

Answer 2

Any ideas?

Answer 3

If it helps this is Algebra.

Answer 4

An analysis of the inequalities by the Mathematica program is attached.

Answer 5

I still dont understand what to do with that information

Answer 6

It just rewrites the question

Answer 7

I don't understand what the third line is saying

Answer 8

where did the 4+3*2=10 come from and what does that mean?

Answer 9

Would x=4 and y=2 be the maximum while x=0 and y=6 be the minimum or vice versa?
And when the equation is graphed does it curve?

Answer 10

Please I still need help.

Answer 11

why have you been typing for so long but nothing pops up.

Answer 12

x + 3y
( 0<=y<=2 && 0<=x<=4) || (2<y<6 && 0<=x<=6-y) || (y==6 && x==0 )
When y is 6 then x has to be 0 from (y==6 && x==0 ) . Then x+3y is 0 + 3*6 = 18, a
maximum value.

From ( 0 <= y <= 2 && 0 <= x <= 4 ) , x and y can be zero at the same time making
x + 3y = 0, a minimum.

Answer 13

That is about all I can do with this problem.

Answer 14

So how do you graph it though

Answer 15

And thanks for your help so far

Answer 16

Don't think I can help you on the graphing at this time.
Sorry about that.

Answer 17

thanks anyway

Answer 18

Have good day.
