In Exercises 25-34, use the matrix capabilities of a graphing utility to find the inverse of the matrix (if it exists).

$\left[ \begin{array}{r} 10 & 5 & -7 \\ -5 & 1 & 4 \\ 3 & 2 & -2 \end{array} \right]$

$A^{-1}=\left[ \begin{array}{ccc}{-10} & {-4} & {27} \\ {2} & {1} & {-5} \\ {-13} & {-5} & {35}\end{array}\right]$

I'm going to be using the free open source computer. Ouch! Persistent or C A s called Maxima for solving these problems were less us to do it with the computer. So imax about you can enter a matrix in a couple of ways. Oh, for the second problem. Well, Internet by hand we have. And bye. Mine seven minus 514 and three to minus two chicken, huh? And then invert the proven Yes, he's out, you know, and there is our answer.
