Multiple Choice

Find the inverse, if it exists, for the matrix.
- $$\left[ \begin{array} { r r } 2 & 3 \\0 & - 1\end{array} \right]$$

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