QuestionEvaluate the matrix expression:
$$2\begin{bmatrix} -5 & -8 \\ 6 & -7 \\ 4 & -1 \end{bmatrix} + \begin{bmatrix} -2 & -9 \\ 8 & -2 \\ 5 & 6 \end{bmatrix} - \begin{bmatrix} 5 & 5 \\ 2 & -1 \\ -9 & 0 \end{bmatrix}$$
Simplify the resulting matrix.

Studdy Solution
Calculate the result of the addition and subtraction.
$$\left[\begin{array}{rr} -10-2-5 & -16-9-5 \\ 12+8-2 & -14-2+1 \\ 8+5+9 & -2+-0\end{array}\right] = \left[\begin{array}{rr} -17 & -30 \\ 18 & -15 \\ 22 &4\end{array}\right]$$The resulting matrix is$$\left[\begin{array}{rr} -17 & -30 \\ 18 & -15 \\ 22 &4\end{array}\right]$$
