The number of games, g, to be played with n teams can be written by the following equation: g=n^2-n if there are to be 132 games
Tema [17]
The equation that describes the relation between the number of games (g) and the number of teams (n) is given as follows:
g = n^2 - n

Now, we are given that the number of games is 132. This means that g=132. To know the number of teams, substitute with the given g in the given equation as follows:
g = n^2 - n
132 = n^2 - n
n^2 - n - 132 = 0 .......> factorize this expression
(n-12)(n-11) = 0
This means that:
either n = 12 teams
Or n = -11 teams (this solution is rejected as the number of teams cannot be negative)

Therefore, based on the above calculations, if the number of games is 132, then, the number of teams is 12

What is the slope of the line represented by the equation y- 6 = 2(x+3)?
OLga [1]
*Remember that slope : is y=mx+b
And m is slope and b is the y-intercept -

In this equation y-6=2(x+3)
m is 2 because if u multiply 2 to (x+3) it will become 2x+6
since m is 2 and b is 6
The slope is 2
And the y-int. is 6

So the slope is 2.
