Use a graphing calculator to find the inverse of each matrix.
50.
$[\begin{matrix} 25 & - 4 \\ - 35 & 6 \end{matrix}]$

Short Answer

Expert verified

The inverse of the given matrix, obtained using a graphing calculator is

[\begin{matrix} \frac{3}{5} & \frac{2}{5} \\ \frac{7}{2} & \frac{5}{2} \end{matrix}]

Step by step solution

– State the concept

The inverse of a matrix can be obtained by using a graphing calculator. This can be achieved by inputting the number of rows and columns and then inputting each element of the matrix row-wise in order.

– List the given data

The given matrix is

[\begin{matrix} 25 & - 4 \\ - 35 & 6 \end{matrix}]

– Calculate the inverse

Inputting the size of the given matrix, that is 2 rows and 2 columns and each element of the matrix row-wise, that is, \[25,-4,-35,6\] in order in a graphing calculator, the inverse of the matrix is obtained as:

\[\left[ \begin{matrix}

\frac{3}{5} & \frac{2}{5} \\

\frac{7}{2} & \frac{5}{2} \\

\end{matrix} \right]\] $25, - 4, - 35, 6$
