When we want to find the distance between two integers using the difference, the best way is to plot them on number line. And then count distance between them. For example -3 and -1. But distance can not be negative.
combining like terms means to get rid of one factor on both sides of the equation.
Empirical data are gathered from experiments. This does not hold true for all species at all times. But the only way to know a certain datum for a certain specie at a certain situation, you do an experiment. However, theoretical data is more on the theory or concept of the situation. It formulates a general equation that could as much as possible hold true to all.
Therefore, this data is empirical.
The answer is A.
Answer:
Step-by-step explanation:
We are given that Jenna knits scarves and sells them on Etsy an online market place.

Where C=Represents the cost in dollars
x=Number of scarves
We have to create a table to show the relationship between the number of scarves x and the cost C
Substitute x=1
$24
Substitute x=2
$28
$32
$36
$40
$44
