Multiple Choice

Find the inverse of the matrix, if it exists
- $$A = \left[ \begin{array} { r r } 1 & 4 \\0 & - 6\end{array} \right]$$

A)
$$\left[ \begin{array} { r r } 0 & - \frac { 1 } { 6 } \\1 & \frac { 2 } { 3 }\end{array} \right]$$

B)
$$\left[ \begin{array} { l r } 1 & - \frac { 2 } { 3 } \\0 & - \frac { 1 } { 6 }\end{array} \right]$$

C)
$$\left[ \begin{array} { r r } 1 & \frac { 2 } { 3 } \\0 & - \frac { 1 } { 6 }\end{array} \right]$$

D)

$$\left[ \begin{array} { r r } - \frac { 1 } { 6 } & \frac { 2 } { 3 } \\0 & 1\end{array} \right]$$
