Answer:
D) 18 freshman, 18 sophmores, 30 juniors, 30 seniors
Step-by-step explanation:
ratio given:
320 : 300 : 500 : 510
320 = 300 and 500 = 510
therefore ratio of 300 : 300 : 500 : 500
Ratio of 300 : 500 = 18 : 30
18 : 18 : 30 : 30
For this case we have to by definition:
If two lines are parallel then their slopes are equal.
If two lines are perpendicular then the product of their slopes is equal to -1.
We have the following equations:
We manipulate the equation to convert it into the slope-intersection form 
Where:
m: It's the slope
y: It is the cut-off point with the y axis.
So:
From the second equation given we have:
We manipulate:
It is observed that the slopes are equal, so the lines are parallel,
ANswer:
The lines are parallel.

Answer:
Yes, GCF stands for (greatest common factor)
so to find it do this:
List the prime factors of each number.
Circle every common prime factor — that is, every prime factor that's a factor of every number in the set.
Multiply all the circled numbers. The result is the GCF.
