Question

A gardener will use up to 250 square feet for planting flowers and vegetables. He wants the area used for flowers to be at least three times the area used for vegetables. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and that y satisfy these requirements.

Answer 1

All I need are the equations and I can fill it out from there....

Answer 2

Answer 3

x should be 3 times superior than y, meaning x>=3y.

Answer 4

right...

Answer 5

Answer 6

@thomaster @nincompoop

Answer 7

That gives you the system:
x>=3y
x+y=250

Answer 8

there's more to it than this

Answer 9

If you draw the two equations I gave you above you'll get the exact same two graphs ^^

Answer 10

I did draw the equations- that's whats in the picture.

Answer 11

Another (or more) equation is missing. This doesn't give me anything to shade

Answer 12

Well you also know that x>0 and y>0

Answer 13

I was waiting for you to give me that.

Answer 14

Because areas are never negative !

Answer 15

areas are never negative...? huh?

Answer 16

Well yeah... Unless you've already seen a piece of land that has a negative area..

Answer 17

you're not helping me. i dont have any idea what you're talking about

Answer 18

Ok this is a very easy definition of what an area is http://www.mathsisfun.com/definitions/area.html
I wasn't trying to make fun, I actually though you knew what an area was, sorry :/

Answer 19

I know what area is... I was talking about shading and you were talking about negatives

Answer 20

Don't mind that, you have 4 inequalities you can use to shade
x>=3y
x+y<=250 (cause gardener will use up to 250 square feet)
x>=0
y>=0
Show me what you get !

Answer 21

sorry, i've moved on from the question... my session timed out.

Answer 22

thanks anyway
