Determine whether the two matrices are inverses of each other by computing their product.
-$\left[\begin{array}{rr}-5 & -1 \ 6 & 0\end{array}\right],\left[\begin{array}{r}0 \frac{1}{6} \ -1 \frac{5}{6}\end{array}\right]$

Question

Quizplus · Accepted Answer

The product of the matrices is not the identity matrix, so they are not inverses of each other.

Determine Whether the Two Matrices Are Inverses of Each Other [−5−160],[016−156]\left[\begin{array}{rr}-5 & -1 \\ 6 & 0\end{array}\right],\left[\begin{array}{r}0 \frac{1}{6} \\ -1 \frac{5}{6}\end{array}\right][−56​−10​],[061​−165​​]
