The values of the matrix is a = -40, b = 16, c = 40, d = 50.
What is a matrix?
A matrix is an arrangement of numbers, expressions or symbols arranged in rows and columns as a rectangular array. These rows and columns define the size or dimension of a matrix.
For the given situation,
The matrix is
[tex]\left[\begin{array}{ccc}4&-1&-4\\0&5&-2\\0&8&10\end{array}\right] = \left[\begin{array}{c}-7&-11&22\end{array}\right][/tex]
The operation on matrix is
[tex]-8R2- > R2[/tex] and
[tex]5R3- > R3[/tex]
⇒ [tex]\left[\begin{array}{ccc}4&-1&-4\\0&-40&16\\0&40&50\end{array}\right] = \left[\begin{array}{c}-7&88&110\end{array}\right][/tex]
On comparing this equation with the given equation,
[tex]a=-40, b=16, c=40, d=50[/tex]
Hence we can conclude that the values of the matrix is a = -40, b = 16, c = 40, d = 50.
