Answer:

The matrix would be:

-1  2

12  2

6  3

-3  -4

Step-by-step explanation:

Took the quiz.

The matrix representation that results from the transformation will be:

[tex]\left[\begin{array}{ccc}-1&2\\0&4\\12&2\\-3&-4\end{array}\right][/tex]

Given the elementary matrix

[tex]\left[\begin{array}{ccc}-1&2\\0&4\\6&3\\-3&-4\end{array}\right][/tex]

The question required us to transform the matrix by using the elementary row operator 2R₃-R₂

Applying the transformation will create a new Row 3 as shown below:

  • New Row 3 Column 1 <-> 2(6) - 0 = 12
  • New Row 3 Column 2 <-> 2(3) - 4 = 6 - 4  = 2

The equivalent matrix will be:

[tex]\left[\begin{array}{ccc}-1&2\\0&4\\12&2\\-3&-4\end{array}\right][/tex]
