Answer:
Step-by-step explanation:
Let us assume that if possible in the group of 101, each had a different number of friends. Then the no of friends 101 persons have 0,1,2,....100 only since number of friends are integers and non negative.
Say P has 100 friends then P has all other persons as friends. In this case, there cannot be any one who has 0 friend. So a contradiction. Hence proved
Part ii: EVen if instead of 101, say n people are there same proof follows as
if different number of friends then they would be 0,1,2...n-1
If one person has n-1 friends then there cannot be any one who does not have any friend.
Thus same proof follows.
Answer:y = 3x + 5 is a linear equation in two variables and it has infinite possible solutions.

Answer:
53 degrees
Step-by-step explanation:
since 180 is a straight line and 90 is half of that, all you need to do is take 37 away from 90 and you get 53
Answer:
C, D
Step-by-step explanation:
1/5 is .20 which is 20%
4/20 is equal to 1/5 which is 20%

(-6,-7) and (2,-7)
So you would do m=y2-y1/x2-x1
(x1,y1) is (-6,-7) and (x2,y2) is (2,-7)
So you get
m=[-7-(-7)]/[2-(-6)]
m=0/2+6
m=0/8
m=0
So the slope is 0. I hope that helps!
