They dont hold, cause t is has to be greater than or equal to zero, but less than or equal to 2+s

Huh? They don't hold? :confused:

These inequalities follow straight from your problem statement - they have to hold!

The only question is, what restrictions do they place on s and t exactly?

Yes, t has to be greater than or equal to zero and less than or equal to 2+s.

But the 2nd and 3rd inequality place further restrictions on t... but which restrictions? - February 20th 2013, 12:45 PMTweetyRe: Linear Algebra help Matrix
?

I really am not getting it, and i dont know how any of this makes t = 0. and makes s have only one value? - February 20th 2013, 12:48 PMILikeSerenaRe: Linear Algebra help Matrix

Well, you didn't say what you get if s=2, or s=0...

Which inequalities do you get in those cases?

Alternatively can you make a graph with:

- s on the horizontal axis

- t on the vertical axis

- the line l given by t=(-4 + 7s)/9

- the line m given by t=(-4 + 7s)/19

We would be looking for values of t that are above line l and below line m. - February 21st 2013, 04:33 AMTweetyRe: Linear Algebra help Matrix
