Which answer choice shows that the commutative property does not hold for matrix multiplication?
Bess [88]

Given:

The matrix statements in the options.

To find:

The answer choice that show the commutative property does not hold for matrix multiplication.

Solution:

We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then

AB\neq BA

Let us assume,

A=\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\text{ and }B=\begin{bmatrix}1&3\\8&5\end{bmatrix}

According to the above property of the matrix, we get

\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\begin{bmatrix}1&3\\8&5\end{bmatrix}\neq \begin{bmatrix}1&3\\8&5\end{bmatrix}\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}

Therefore, the correct option is B.

Black_prince [1.1K]

Answer:

<h2>y = 1</h2>

Step-by-step explanation:

\frac{24y}{8}  = 3 \\

<u>Divide both sides by 3</u>

\frac{3y}{3}  =  \frac{3}{3}  \\

We have the final answer as

<h3>y = 1</h3>
