Multiple Choice

Find the inverse of the matrix, if it exists
- $$A = \left[ \begin{array} { r r } 5 & 0 \\- 4 & - 6\end{array} \right]$$

A)
$$\left[ \begin{array} { c c } - \frac { 1 } { 6 } & 0 \\- \frac { 2 } { 15 } & \frac { 1 } { 5 }\end{array} \right]$$

B) $\mathrm { A }$ is not invertible

C)
$$\left[ \begin{array} { c c } \frac { 1 } { 5 } & 0 \\\frac { 2 } { 15 } & - \frac { 1 } { 6 }\end{array} \right]$$
D)
$$\left[ \begin{array} { c c } \frac { 1 } { 5 } & 0 \\- \frac { 2 } { 15 } & - \frac { 1 } { 6 }\end{array} \right]$$
