This system of equations has been placed in a matrix:

[tex]\[ \begin{array}{l} y = 700x + 200 \\ y = 5000 - 75x \end{array} \][/tex]

Complete the matrix by filling in the missing numbers.

Sagot :

Sure, let's solve the given system of equations and represent them in matrix form. We'll use the equations provided:

1. [tex]\( y = 700x + 200 \)[/tex]
2. [tex]\( y = 5000 - 75x \)[/tex]

First, we'll convert each equation to standard form [tex]\( Ax + By = C \)[/tex].

### Equation 1:
[tex]\( y = 700x + 200 \)[/tex]

Rearrange it to the standard form:
[tex]\[ y - 700x = 200 \][/tex]
This can be written in the form of:
[tex]\[ -700x + y = 200 \][/tex]
So, the corresponding row for the matrix will be:
[tex]\[ [-700, 1, 200] \][/tex]

### Equation 2:
[tex]\( y = 5000 - 75x \)[/tex]

Rearrange it to the standard form:
[tex]\[ y + 75x = 5000 \][/tex]
This can be written in the form of:
[tex]\[ 75x + y = 5000 \][/tex]
So, the corresponding row for the matrix will be:
[tex]\[ [75, 1, 5000] \][/tex]

Now, let's assemble the matrix using rows from the equations above:

[tex]\[ \begin{array}{ccc} -700 & 1 & 200 \\ 75 & 1 & 5000 \\ \end{array} \][/tex]

Therefore, the completed matrix representing the given system of equations is:

[tex]\[ \left[\begin{array}{ccc} -700 & 1 & 200 \\ 75 & 1 & 5000 \\ \end{array}\right] \][/tex]

This matrix succinctly holds the coefficients and constants from the system of equations given.
