Question

Write the augmented matrix for each system of equations.

Answer 1

the augmented matrix is made from the coefficients of the several variables and the solution constants. A is the correct answer

Answer 2

Answer:

(A)

Step-by-step explanation:

An augmented matrix is a matrix that is obtained by attaching  the columns of two given matrices, usually for the purpose of performing the same elementary row operations on each of the given matrices.

The given system of the equations are:

$9x-4y-5z=9$

$7x+4y-4z=-1$

$6x-6y+z=-5$

Thus, the augmented matrix will be of the form:

$\bigl(\begin{smallmatrix}9 & -4 &-5:9 \\ 7 &  4 &-4:-1 \\  6& -6 &1:-5 \end{smallmatrix}\bigr)$

Hence, option A is correct.
