A. the first one will give you a perpendicular line to BA
No. Because sides JM and KL have different slopes from sides AD and BC .
The formula of a slope:
For AD:
We have the points A(2, -2) and D(1, -4). Substitute:
For JM:
We have the points J(4, -4) and M(2, -9). Substitute:
----------------------------------------
Another argument.
No. Because the MJ is not twice as long as AD.
The formula of the length of a segment:
The length of AD:
The length of MJ:
here is the graph
i learned this in math lol lol
Answer: 15 players.
Step-by-step explanation:
number of games played in the tournament = 105 games
nunber of games played by each player against another = 1 game each.
Solution:
Number if player who participated in the tournament.
if each player played a game against every other player, and they were 105 games played at the tournament.
n ( n – 1 ) /n = m
= n ( n – 1 ) 2 = 105
open the bracket
n^2 – n = 210
n^2 – n – 210 = 0
( n – 15 ) ( n + 14 ) = 0
n = 15
15 players Participated In the tournament.
