Question

Can someone help me with this? I’m having quite a lot of trouble solving it. It’s a practice problem from my prep guide

Answer 1

`A\text{ = }\begin{bmatrix}{-3} & {5} & {2} \\ {8} & {-1} & {3} \\ {} & {} & {}\end{bmatrix}`

We are to multiplied the given matrix by a scalar (-8), that is we multiply each element by -8.

`-8.A\text{ = }\begin{bmatrix}{-8.-3} & {-8.5} & {-8.2} \\ {-8.8} & {-8.-1} & {-8.3} \\ {} & {} & {}\end{bmatrix}`

`\begin{bmatrix}{24} & {-40} & {-16} \\ {-64} & {8} & {-24} \\ {} & {} & {}\end{bmatrix}`
