They are neither,they intersect but not at a 90 degree angle
Answer:
Infinitely many solutions.
Step-by-step explanation:
The two sides are the exact same therefore x can be anything
The standard deviation of 36,18,12,10 and 9 is 10
3x + 8 = 3x + []
Subtract 3x from both sides.
[] = 8
If you want no values of x, it can be any positive value other than 8.
If you want all values of x, the value must be 8.
If you want only one value of x, it is impossible because both equations have the same slope.
