Prime numbers are numbers that have only one factor pair; 1 and themselves.

Let's start from 21.

21 = 1 x 21, 3  x 7.
This has two factor pairs, this is not prime.

Let's try 22.

22 = 1 x 22, 2 x 11.
This also has two factor pairs, this is not prime.

Let's try 23.

1 x 23.
This is a prime number, as it only has one factor pair; 1 and itself.

23 is your prime number.

I hope this helps!

A hair salon charges a fixed rate of $25.00 for a haircut and an additional $15 for any other services. Write a function to mode
Lynna [10]

Answer:

A

Step-by-step explanation:

The function is f(x) = 15x + 25 as 25$ is a fixed rate ( it does not change and is always charged) when 15$ for any other service which can be anything, a costumer can have 0 services other than the hair cut which gives f(0). As for the question, it's asking for haircut, shampoo, highlight, and blow dry so that is 3 other services other than the fixed haircut which means f(3). substitute x=3 in the function to get 15(3) + 25 = 45+25 = 70.
