Answer:
4y
Step-by-step explanation:
To find the greatest common factor of 2 numbers, factor both of the numbers:
4: 1, 2, 4
12: 1, 2, 3, 4, 6, 12
The greatest factor here in both of these lists is 4. These numbers also both have a factor of y, so you multiply those together and get 4y.

Answer:
y-3=3/5x
Step-by-step explanation:
y-y1=m(x-x1)
Where m=slope and (x1, y1) is a point on the line.
m=(y2-y1)/(x2-x1)
m=(0-3)/(-5-0)
m=-3/-5
m=3/5
y-3=3/5(x-0)
y-3=3/5(x)
y-3=3/5x
Complementary means sum = 90, so 90-57 to get the other angle at 23 degrees
Supplementary means sum = 180, so 180-52 to get the other angle at 128 degrees
Ok so I have a way you can find the answers. Go look online and use Socratic
This arithmetic sequence has first term 6 and common difference -1. The general formula is
an = a1 +(n-1)d
For your sequence, this is
an = 6 +(n-1)*(-1)
an = 7 - n
