Question

help, picture attached. Show working thanks.

Answer 1

sry about the long wait, what's on your mind?

Answer 2

well i need help with mainly c and d

Answer 3

is there a typo in the problem? I see a line with a negative slope in the graph, but all of the equations have positive slopes.

Answer 4

nope the negative one is inequality 5

Answer 5

if u rearrange it to y on the left side u can see that x is negative

Answer 6

oh totally missed that one lol, one sec

Answer 7

yeh kk thanks

Answer 8

with part C), you simply plug x = 10 and y = 5 into each inequality and see if it satisfies every inequality

Answer 9

so x > 0 ---> 10 > 0 ... which is true

y > 0 ----> 5 > 0 ... which is true

y <= x/2 -----> 5 <= 10/2 ---> 5 <= 5... which is true

etc etc

Do you see where this is going?

Once you've shown that all inequalities are true, this will show us that they are complying with the restraints

Answer 10

kk got it.

Answer 11

how about d) ?

Answer 12

have you plotted every inequality?

Answer 13

yeh

Answer 14

hmm I'm not entirely sure, but does it give you an objective function to maximize or minimize?

Answer 15

nope, all they said is required in part d)

Answer 16

alright one second

Answer 17

I guess you don't need the objective function in this case. In this case, all you need to do is find the corner points of the feasible region and determine which ones have the max and min value of x.

Answer 18

but it says min=17 & max=18 how are those answers obtained?

Answer 19

hmm not exactly sure, but it looks like they found the max value of 18 by testing the point (18,6). But the issue here is that there isn't an objective function to go by.

Answer 20

yeh so I am still confused as how they got 17 & 18??

Answer 21

I have to read this whole thing again! D:

Answer 22

lol, please help! It's urgent!
