Slope m=(y2-y1)/(x2-x1)=(10-4)/(4-2)=6/2=3

y = mx+b
y=3x+b
Take point (2,4),
4=3*2+b
4=6+b

Solve the matrix equation below. What is the value of x in the new matrix?

andrew11 [14]

The new matrix that is formed by the 3A + B is given below. Then the value of x is 102.

$\begin{bmatrix} w & z \\y & z \\\end{bmatrix} = \begin{bmatrix} 46 & 102 \\15 & -2 \\\end{bmatrix}$

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The $a_{ij }$ element in a matrix, such as M, refers to the i-th row and j-th column element.

The matrices are given below.

$\rm A = \begin{bmatrix}9 & 27 \\0 & 6 \\\end{bmatrix}\\\\\\B = \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}$

Then the new matrix is given as 3A + B. Then we have

$\rm 3A + B =\begin{bmatrix} w & z \\y & z \\\end{bmatrix}\\\\\\3A + B =3 \times \begin{bmatrix}9 & 27 \\0 & 6 \\\end{bmatrix} + \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}\\\\\\3A + B = \begin{bmatrix}27& 81\\0 & 18\\\end{bmatrix} + \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}\\\\\\3A + B = \begin{bmatrix} 46 & 102 \\15 & -2 \\\end{bmatrix}$
