Write the augmented matrix for each system of equations. 10x=10 -5x-8y=9

koban [17]

ANSWER

$\left[ { \begin {array} {cc} 10&0& | 10\\-5&-8& | 9\\ \end {array}} \right]$

EXPLANATION

The given system of equations is

10x=10

-5x-8y=9

We can rewrite this as:

10x+0y=10

-5x-8y=9

The augmented matrix is the combination of the coefficient matrix and the constant matrix.

The coefficient matrix is

$\left[ { \begin {array} {cc} 10&0\\ - 5& - 8\\ \end {array}} \right]$

The constant matrix is

$\binom{10}{9}$

The augmented matrix is

$\left[ { \begin {array} {cc} 10&0& | 10\\-5&-8& | 9\\ \end {array}} \right]$
