Write the coefficient matrix and the augmented matrix of the given system of linear equations. 7x_1 + 6x_2 = 6
2x_1 - 8x_2 = 4
What is the coefficient matrix?

The coefficient matrix is represented by .

The augmented matrix is represented by .

Step-by-step explanation:

From Linear Algebra we know that a system of linear equations with variables can be represented as a matrix product:

Where:

- Coefficient matrix, a matrix.

- Variable matrix, a matrix.

- Equivalence matrix, a matrix.

Then, the given system is represented as:

The coefficient matrix is represented by .

The augmented matrix consist in the union of the coefficient and equivalence matrices. That is:

The augmented matrix is represented by .

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
