This is the concept of combination, the number of ways 4 different color can be chosen from 9 different colors will be:
9C4
=(9!)/(4!(9-4)!)
=362,880/(24×120)
=362,880/2880
=126
thus the number of ways is 126 ways
Answer:
x>-2.5
Step-by-step explanation:

The demoin is all real numbers greater than 6
B.
It says x = y + 3. So what they did was put y + 3 in the place of x.
A segment is bounded by two endpoints.
The two segments can have up to two common points
Assume the line segments are AB and CD where the length of AB is greater than the length of CD.
<u>The possibilities are:</u>
- <em>A point of segment CD lies on segment AB</em>
- <em>Both points of segment CD lie on segment AB.</em>
<em />
See attachment for both possibilities.
Hence, it is possible for the two segments to have two common points.
