Use a graphing utility to find the inverse of the matrix, if it exists. Round answers to two decimal places, if necessary.
-$$\left[ \begin{array} { r r r }
- 16 & 3 & 28 \
5 & - 14 & 15 \
34 & 25 & 2
\end{array} \right]$$
A) $\left[ \begin{array} { r r r } - 0.01 & 0.02 & 0.01 \ 0.02 & - 0.03 & 0.01 \ 0.02 & 0.02 & 0 . \end{array} \right.$
B) $\left[ \begin{array} { r r r } - 0.02 & 0.03 & 0.02 \ 0.02 & - 0.04 & 0.01 \ 0.02 & 0.02 & 0.00 \end{array} \right]$
C)
$ \left[\begin{array}{rrr}-0.01 & 0.03 & 0.02 \ 0.02 & -0.03 & 0.01 \ 0.02 & 0.02 & 0.01\end{array}\right] $
D)
$ \left[\begin{array}{rrr}-0.02 & 0.03 & 0.02 \ 0.02 & -0.04 & 0.02 \ 0.02 & 0.02 & 0.01\end{array}\right] $
