The augmented matrix for the given linear equations will be constructed as follows

\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right] \left[\begin{array}{ccc}5&\\0\\3\end{array}\right]

<h3>What will be the augmented matrix of the given linear equations?</h3>

The augmented matrix is generally a matrix form of the given linear equations and the coefficient of the variables are arranged in the form of a matrix.

The given equation has three variables so the matrix form will be of 3\times3

The given linear equations are

x-y-4z=5\\2x+0y+2z=0\\4x+y+z=3

From the above equations, we will make an augmented matrix.

\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right] \left[\begin{array}{ccc}5&\\0\\3\end{array}\right]

The first equation will be followed by the first row of the matrix and the rest will be followed the same.

Thus the augmented matrix for the given linear equations will be constructed as follows

\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right] \left[\begin{array}{ccc}5&\\0\\3\end{array}\right]

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)

What is an independent variable <br><br>what is an dependent variable <br><br><br>​
N76 [4]

An independednt variable is a variable that doesnt need any support Dependent is where there is variable, but it depends on something else.

For example,

y=2x+1

y is dependent, becuase it depend on 2x+1

x is independent, beucase it doesnt need to depend on anything.

Write the 2-digit number that matches the clues. My number has a tens digit that is 8 more than the ones digit. Zero is not one
laila [671]
Firstly attention should pe paid to the exact words given in the problem and then only the answer can be easily deduced.
It is a 2 digit number and that is said in the problem
Now For the tens digit it has been said that it is 8 more than the ones digit. The ones digit cannot be zero and that is already mentioned in the problem.
So if we take the ones digit to be 1, then the tens digit will be= 8 +1
                                                                                                 = 9
Now if we take the ones digit to be 2, then the tens digit will be = 2 + 8
                                                                                                     = 10
So it cannot be 2 as the tens digit takes the number to a 3 digit number and it is not possible.
So the answer to this problem is 91.
