question 79

Multiple Choice

Determine the inverse of the given matrix, if possible. Otherwise, state the matrix is singular.
- $$A = \left[ \begin{array} { r r } - 5 & - 4 \\- 25 & - 20\end{array} \right]$$

• A) \(A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 8 } & \frac { 1 } { 10 } \\ - \frac { 1 } { 8 } & - \frac { 1 } { 8 } \end{array} \right]\)
• B) Singular matrix
• C) \(A ^ { - 1 } = \left[ \begin{array} { c c } \frac { 1 } { 8 } & - \frac { 1 } { 10 } \\ \frac { 1 } { 8 } & - \frac { 1 } { 8 } \end{array} \right]\)
• D) \(A ^ { - 1 } = \left[ \begin{array} { r r } - \frac { 1 } { 8 } & - \frac { 1 } { 10 } \\ \frac { 1 } { 8 } & \frac { 1 } { 8 } \end{array} \right]\)
