Solve the system by using a matrix equation
3x-5y=3
3x-4y=3

B. (1,0)

Step-by-step explanation:

1. We will use the matrix method to solve this problem.

3-53

3-43

2. Apply to Row2 : Row2 - Row1.

3-53

010

3. Simplify rows.

3-53

010

Note: The matrix is now in row echelon form.

The steps below are for back substitution.

4. Apply to Row1 : Row1 + 5 Row2.

303

010

5. Simplify rows.

101

010

Note: The matrix is now in reduced row echelon form.

6. Therefore,

x=1

y=0

or (1,0).

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
