Multiple Choice

Find the inverse of the matrix, if it exists
- $$A = \left[ \begin{array} { r r } - 3 & - 4 \\3 & - 4\end{array} \right]$$

• A) \[\left[ \begin{array} { r r } - \frac { 1 } { 8 } & \frac { 1 } { 6 } \\ - \frac { 1 } { 8 } & - \frac { 1 } { 6 } \end{array} \right]\]
• B) \(\left[\begin{array}{cc} -\frac{1}{6} & \frac{1}{6} \\ -\frac{1}{8} & -\frac{1}{8} \end{array}\right]\)
• D) \(\left[\begin{array}{c} -\frac{1}{6}-\frac{1}{6} \\ \frac{1}{8}-\frac{1}{8} \end{array}\right]\)
