Question

Mark and Nancy are making punch for a party and are using two types of juice: pineapple and papaya. The total number of quarts must be more than 9 but less than 15. They should use at least 4 quarts of each type. We want to find out how many quarts of each juice they should buy.
List any three ordered pair solutions from your graph in #1.

Answer 1

Okay. We get 4 equations, right?
x>=4
y>=4
x+y>=9
and x+y <= 15

To find vertices, you just need to pic two of those equations and figure out if (and where) they cross.

Answer 2

yeah...can u just give me the ordered pairs?

Answer 3

Nope. I don't roll like that.

Answer 4

aww

Answer 5

please! this 1 time?!

Answer 6

Well x+y >= 9 and x+y <=15 don't cross because the two lines have the same slope. -1.

So you need to get your ordered pairs by matching up the other equations.
Use x=4 and y = -x+9 to get one ordered pair.
Use y = 4 and y = -x+15 to get another.
Use x = 4 and y = 4 to get another.

Answer 7

yay! thanks!
