Graph the system of equations. Then determine whether it has no solution, one solution, or infinitely many solutions. If the system has one solution name it.

x - 3y = -3
x + 3y = 9

see attached.

Step-by-step explanation:

because the lines intersect at only 1 point, the system has only 1 solution at (3,2)

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%
