1.
Consider a group of n objects. Assume we want to form groups of r, from these n objects.
There are in total
many ways of doing so.
where, r! is "r factorial", calculated as 1*2*3*...*(r-1)*r
2.
C(x, 2) is the total number of pairs out of x objects, that we can form.
so let the x objects represent the x teams, and 2, represent a group of 2, which means a game.
The total number of games is:
n(x)=2*C(x, 2) =
Remark, we multiplied by 2, since there will be 2 matches for each pair of teams.

Answer:
Step-by-step explanation:
Notice that with the provided information they are given you not ust the slope of the line (-2), but also the y-intercept (the point where the line crosses the y-axis which happens when x=0).
So you can directly write the equation of the line in slope-intercept form [ where "m" is the slope and "b" the y-value when x=0].
Such gives us:
Answer:
A. 60°
Step-by-step explanation:
3tan^3 x= tan x
3tan^2x = 1
tan^2 x = 1/3
tan x = 1/
x = 60°
