By definition we have to:
A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
The initial set or starting set is also called the domain; the final set or set of arrival, meanwhile, can be called codomain.
We have the following information:
{(-5.2), (-2.5), (0.7), (0.9)}
The data does not represent a function because two different values of the range belong to an element of the domain:
(0.7)
(0.9)
Answer:
The relation is not a function.
The difference in volume is 125.6 cm^3, so the difference in height will be
.. 125.6 cm^3/(3.14*(2 cm)^2) = 10 cm

Have a wonderful day!
First, set a variable.
Let x = the number of songs bought.
Each song costs 2 dollars. So, we have our first term: 2x.
And there is a fee of 5 dollars for using the website.
2x + 5
And she can't spend any more than 40 dollars. Which means she can spend 40 and under.
So, 2x + 5 ≤ 40 is the answer.
Answer:
x = -2y
Step-by-step explanation:
Step 1. x + 2y = 0
Step 2. x + 0 = -2y
Step 3. x = -2y
