Which of the following best describes the solution to the system of equations below? -8x + 3y = -9 9x - 3y = 9 A. The system of equations has exactly one solution where x = 0 and y = -3. B. The system of equations has exactly one solution where x = 8 and y = 3. C. The system of equations has no solution. D. The system of equations has infinitely many solutions.

Option A. The system of equations has exactly one solution where x = 0 and y = -3

Step-by-step explanation:

we have

----> equation A

-----> equation B

Solve the system by elimination

Adds equation A and equation B

find the value of y

substitute the value of x in equation A or equation B

so

The solution of the system is the point (0,-3)

therefore

The system of equations has exactly one solution where x = 0 and y = -3

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
