Question

1. -/1 points consider the following. ( b=left\begin{array}{cc}-6 & 6 \\ 8 & 4end{array}

ight, quad c=left\begin{array}{cc}0 & 5 \\ 4 & -9end{array}
ight ) use the matrices to perform the indicated operation if possible. (if an answer is undefined, enter undefined into any cell of the matrix.) ( 3 c+b )

Explanation:

Step1: Calculate \(3C\)

Multiply each element of matrix \(C=

$$\begin{bmatrix}0&5\\4&-9\end{bmatrix}$$

\) by \(3\).

$$ 3C = 3\times
LATEXBLOCK1
=
LATEXBLOCK2
=
LATEXBLOCK3
$$

Step2: Calculate \(3C + B\)

Add matrix \(3C=

$$\begin{bmatrix}0&15\\12&-27\end{bmatrix}$$

\) and \(B=

$$\begin{bmatrix}-6&6\\8&4\end{bmatrix}$$

\).

$$
LATEXBLOCK6
$$

Answer:

$$
LATEXBLOCK0
$$
