1y + 2x = 0 ⇒ -2x - 1y = 0
4x + 1y = 3 ⇒ <u>4x + 1y = 3</u>
<u>2x</u> = <u>3</u>
2 2
x = 1.5
4(1.5) + y = 3
6 + y = 3
<u>- 6 - 6</u>
y = -3
(x, y) = (1.5, -3)
Y + 2 = -3(x - 4) [given: y = -2 ]
-2 + 2 = -3(x - 4)
0 = -3x + 12
3x = 12
x = 12/3
x = 4
Answer: 4
The statistic that the coach should study is mean or the
average score of the two teams. If the coach wants to know if football players
who warm up before a game will score more points than those who don't warm up.
He will break the team up into two groups and make sure each player gets equal
time on the field. He will then count how many points each player makes during
the game. After counting them, add the scores of the group that he divided and
then divided it by the number of player in that group to get an average score
on teams that warm up or do not warm up before the game.
214
* 3
-------
642
this is your answer but you can tell that 7+3=10 so you just times 3 by 214 that will give you the 214th term in the sequence hope that this helps
