Permutation is when the order of arrangement matters
Combination is when the order of arrangement does not matter

Distributing 8 different books among 21 children is a combination because the order of arrangement does not matter

The questions is 'how many ways to  pick 8 from 21'

\frac{21!}{(21-8)!8!}= 203490 ways of distributing 8 books among 21 children

Solve the following system of equations graphically. y - 4 = 0 2x - y - 2 = 0 What is the solution set?
tatiyna

Answer:

{(x,y)|(x=3,y=4)}

Step-by-step explanation:

The given system of equations is;

y-4=0...(1)

and

2x-y-2=0...(2)

We rewrite the equations in the standard form to get:

y=4...(3)

2x-y=2...(4)

We now substitute equation (3) into equation (4) to get:

2x-4=2

Group similar terms:

2x=2+4

2x=6

Divide both sides by 2

\frac{2x}{2}=\frac{6}{2}

This implies that:

x=3

Therefore the solution set is:

{(x,y)|(x=3,y=4)}
