h(x)= 6x - 17

Let's find h(8)

h(8) = 6(8) - 17

h(8) = 48 - 17

h(8) = 31

Construct an augmented matrix for this linear system: x − y − 4z = 5 2x 2z = 0 4x y z = 3.
Crazy boy [7]

The augmented matrix is,

\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)

We have given system of linear equation is,

x - y - 4z = 5,2x + 2z = 0 ,4x +y +z = 3.

<h3>What is the meaning of augmented matrix?</h3>

In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.

So, the first row is

1\ -1\ -4\ 5

the second row is

2\ 0\ 2\ 0

and the third row is

4\ 1\ 1\ 3

Therefore the augmented matrix for this linear system is,

\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)
