How does that work? o.O Sorry, I just haven't done TOO much with matrices yet...

Hmmmm....im sorry i am not sure how to explain you why it is like that....:( it just is like that hmmmm....u can try these...they r pretty good http://www.khanacademy.org/math/algebra/algebramatrices?k

Well, the final answer is a matrix...can you tell me what topic for matrices to watch? I've watched all of them to the extent of Algebra II material.

watch inverting matrices

CalcmathleteBest ResponseYou've already chosen the best response.1
Wouldn't the inverse be \[\left[\begin{matrix}2 & 1 \\ 4 & 4\end{matrix}\right]\]

tell me smth u want to find the inverse of the dw:1343829407799:dw

CalcmathleteBest ResponseYou've already chosen the best response.1
Would I perform this: \[\frac1{12}\left[\begin{matrix}2 & 1 \\ 4 & 4\end{matrix}\right]\]

Yes. I want to find the inverse of what's above in your picture.

Isn't that what I did above? dw:1343829681330:dw

CalcmathleteBest ResponseYou've already chosen the best response.1
Alright, so the answer would be: \[\left[\begin{matrix}\frac16 & \frac1{12} \\ \frac13 & \frac13\end{matrix}\right]\]

Is there supposed to an aboslute value on the A? not sure...I thought that a and d switched places and that b and c negated...maybe I'm wrong?

CalcmathleteBest ResponseYou've already chosen the best response.1
So it would be correct what I did?
