Question

What is 2M? 3 5 M= =: -4 0 6 10 о -8 5 1 3 O -6 -2 6 5 O -4 0 6 10 16. -8 0(ill send a picture of the problem)

Answer 1

Given:

$M=\begin{bmatrix}{3} & {5} & \\ {-4} & {0} & {} \\ {} & {} & \end{bmatrix}$

We are required to find 2M.

To calculate 2M, let's multiply 2 to the matrix M.

Multiply all values inside M by 2

We have:

$\begin{gathered} M\text{ = }\begin{bmatrix}{3} & {5} \\ {-4} & {0} \\ & \end{bmatrix} \\ \\ \\ 2M\text{ = }\begin{bmatrix}{2\times3} & & {2\times5} \\ & {} & \\ {2\times-4} & {} & {2\times0}\end{bmatrix} \\ \\ \\ 2M\text{ = }\begin{bmatrix}{6} & & {10} \\ & {} & \\ {-8} & {} & {0}\end{bmatrix} \end{gathered}$

ANSWER:

$\begin{bmatrix}{6} & & {10} \\ & {} & \\ {-8} & {} & {0}\end{bmatrix}$
