It's a factor. This concept is widely used throughout algebra, and you'll probably bump into it through the end of high school and beyond.
A common use is expressing a term in <em>prime factorization</em>, or reducing a number to its most base parts- primes. For example:
Of course, a number like 13 which is already prime is made up of itself and 1. <em>Factors do not have to be primes.</em> 20 is also reducible through combinations of 1, 2, 4, 5, 10, and 20. Prime factorization is just a handy example.
Basically, factors multiply with each other to create other numbers, and numbers can be reduced down to their factors.
Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.
You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates 
, and the domain is the set of all the x values.
The points on your red line have all coordinates 
, where d starts from 0 and ranges up to 12. So, the domain of the function is ![[0,12]](https://tex.z-dn.net/?f=%20%5B0%2C12%5D%20)
Answer:
both plumbers charge $120 for 3 hours of work
Step-by-step explanation:
1) x=3 and x stands for hours.
2) 120=y and y stands for money charged
so the points (3, 120) show that the plumbers both charge 120 for 3 hrs.
Answer:
the duplicate ratio of a : b
= a²/b²
Step-by-step explanation:
for example:-
for understanding
if u wanna find the duplicate ratio of 4:5
so,
4²/5²= 16/25
•°• 16:25
16:25 is your duplicate ratio of 4:5
Emily bikes 12 miles, generating a donation unit for every 0.75 miles. Her 12 mile ride will generate
12 × 0.75 = 9 donation units. For each of these 9 danation units her mother will donate 80 cents.
It follows that Emily's mom will donate
9 donation units × $0.80 per unit = $7.20.
