Practice problem
What is the inverse of [4−384]\begin{bmatrix}4&-3\\8&4\end{bmatrix}[48−34]?
[43−84]\begin{bmatrix}4&3\\-8&4\end{bmatrix}[4−834]
[110340−15110]\begin{bmatrix}\frac1{10}&\frac3{40}\\-\frac15&\frac1{10}\end{bmatrix}[101−51403101]
[110−34015110]\begin{bmatrix}\frac1{10}&-\frac3{40}\\\frac15&\frac1{10}\end{bmatrix}[10151−403101]
This matrix does not have an inverse.
Type a concept, like “slope” or “photosynthesis”.
