Question

I need the points from the vertices and the min and max. The ANSWERS ONLY Please! :D
22. Function: 5x - 2y
y < or = to 7 - x
3x - 2y < or = to 6
2x + y > or = to -3

Answer 1

y is greater than or equal to 1
\[y \ge 1\]
3(1) + x
3(2)+ x
3(3) + x
etc....

2 is less than or equal to x
x is less than or equal to 4

2\[2\le x \le 4\]
So this number can be less than or equal to 4
4, 3, 2, 1, 0, -1, -2, -3, -4 etc...

\[y \le -1/2x + 2\]

-.50 + 2 = 1.5

so basically less than or equal to 1.5
1.4, 1.3, 1.2, 1.1, 1, 0, etc....

Answer 2

@MathLegend Ya there

Answer 3

I just need the coordinate points and if the equations have a minimum or a maximum

Answer 4

find the intersection of all those lines, then check the function at those numbers

Answer 5

do you know the answers just asking???

Answer 6

can ya give me the answers, I know how to do it

Answer 7

i don't now how to do it quickly, no
the intersection of \(x=4\) and \(y=-\frac{1}{2}x+2\) is \((4,0)\) so you have to check that one

Answer 8

what goes with what

Answer 9

when \(x=2\) you get the point \((2,1)\) so you have to check that one as well

Answer 10

first one is the \(x\) second is the \(y\)

Answer 11

Is it 18, 20, or 22

Answer 12

so you use \(3y + x\) at each point
at \((4,0)\) you get \(3\times 0+4=4\) at \((2,1)\) you get \(4\times 1+2=6\)

Answer 13

Are there are 2 points for #18

Answer 14

wait i made a mistake somewhere

Answer 15

oh it is \(3\times 1+2=5\) for the point \((2,1)\) that is the maximum

Answer 16

these are a royal pain
if you just want the answers, cheat (use technology)

Answer 17

let me see if this works, hold on

Answer 18

It's better to get it from you @satellite73

Answer 19

hell no, i hate these

Answer 20

nice huh
note the syntax, finish quickly

Answer 21

How do you make the > < or = to symbol on the website @satellite73

Answer 22

\leq

Answer 23

@satellite73 on number 20 and 22
