Which system of equations represents the matrix shown below ?

The answer is:

The option that represents the matrix is the option D:

From the statement we know that the matrix is formed with the information obtained from a system of equations:

Being the values of the first column the values of the variable "x"

Being the values of the second column the values of the variable "y"

Being the values of the third column the values of the variable "z"

Being the values of the fourth column the values of the constant numbers (after the equality)

Knowing that, we are looking for a system equation that contains the following equations:

First equation:

Second equation:

Third equation:

Hence, we can see that the option that matches with the matrix is the option D.

Have a nice day!

it is probably the graph on the bottom right.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
