If you have three friends, how many ways can you introduce them to someone?
2 answers:
Answer: 6
Step-by-step explanation:
Given : The number of friends : 3
If we introduce one by one , then the number of ways to introduce them is given by permutations .
We can choose first friend in 3 ways , second in 2 and the third in one way.
Then , the number of ways of introducing 3 friends one at a time is given by :-
Therefore, the number of ways of introducing 3 friends = 6

Answer:
y = x - 2
Step-by-step explanation:
<u>The answer to this problem is a simple plug-in of the given values into the slope-intercept formula.</u>
Slope intercept formula: y = mx + b
(m = slope)
(b = y intercept)
If the equation has a slope of m = , then the slope-intercept form would be:
y = x
If the y-intercept of an equation is (0 , -2), then the slope intercept form would be:
y = mx - 2
<u>Putting both of these values into an equation would give option A:</u>
y = x - 2
