Fine -4A+6B (Picture provided)

Answer:

Option a

$-4A+6B=\left(\begin{array}{ccc}-22&30&32\\-16&-78&48\\42&24&30\end{array}\right)$

Step-by-step explanation:

First multiply matrix A by -4.

Then multiply the matrix B by 6.

When multiplying a matrix by a number x you must multiply each element of the matrix by x.

Then we perform operation -4A

$-4\left(\begin{array}{ccc}-2&6&1\\1&9&-6\\-9&9&-9\end{array}\right)=\left(\begin{array}{ccc}8&-24&-4\\-4&-36&24\\36&-36&36\end{array}\right)$

Now we perform operation 6B

$6\left(\begin{array}{ccc}-5&9&6\\-2&-7&4\\1&10&-1\end{array}\right)=\left(\begin{array}{ccc}-30&54&36\\-12&-42&24\\6&60&-6\end{array}\right)$

Now we add the resulting matrices

$\left(\begin{array}{ccc}8&-24&-4\\-4&-36&24\\36&-36&36\end{array}\right)+\left(\begin{array}{ccc}-30&54&36\\-12&-42&24\\6&60&-6\end{array}\right)=\left(\begin{array}{ccc}-22&30&32\\-16&-78&48\\42&24&30\end{array}\right)$

Copying a given segment is the process in which a given line segment is drawn following the required steps so that both object and image have the same length. Therefore,

i. PQ = 12 cm

ii. MN = 12 cm

Thus, PQ = MN

Construction is a process that requires the use of materials and instruments to produce a required image. This involves following stated or required steps.

A given line segment can be copied by following appropriate steps. Such that both lines would have the same length, and would be parallel to each other or as required.

The given question requires following the stated steps to produce the required construction. Such that line segment NM is the image of PQ, and both have equal length.

The required construction for the question is attached to this answer.
