Practice problem
Find the inverse of the matrix [1329]\begin{bmatrix}1&3\\2&9\end{bmatrix}[1239].
[3−1−2313]\begin{bmatrix}3&-1\\-\tfrac23&\tfrac13\end{bmatrix}[3−32−131]
[9−3−21]\begin{bmatrix}9&-3\\-2&1\end{bmatrix}[9−2−31]
[131233]\begin{bmatrix}\tfrac13&1\\\tfrac23&3\end{bmatrix}[313213]
This matrix does not have an inverse.
Type a concept, like “slope” or “photosynthesis”.
