Question

Which matrix represents the system of equations shown below

Answer 1

its C because you put the question

Answer 2

C) option is correct.

Explanation:

Given : 4x + 2y - 4 and 12x -y - 26.

To find : Which matrix represents the system of equations shown below.

Solution : We have given

4x + 2y - 4 = 0

12x -y - 26 = 0

Expressing Systems of Equations as Matrices:

ax +by = α

cx +dy = β

Can be represent in matrices as
`\left[\begin{array}{ab}a&b\\c&d\end{array}\right] * \left[\begin{array}{ab}x\\y\end{array}\right] =  \left[\begin{array}{ab}\alpha \\\beta \end{array}\right]`.

Then,

On comparison matrix would be

`\left[\begin{array}{ccc}4x&2y\\12x&-y\\\end{array}\right]\left[\begin{array}{ccc}4\\26\\\end{array}\right]`.

Therefore, C) option is correct.
