Answer:
It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.
This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.
Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.
The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.
Answer:
Step-by-step explanation:
Given
Ferret:
Labrador Retriever
Required
Determine the slope
Represent the given as x or y
Taking the weight as explanatory variable;
We have:
x = 2.1; y = 3.4
x = 7.5; y = 70
Slope is calculated as:
<em>Hence, the slope is 12.33</em>

Melissa can drive farther
Answer:
n > 4 is the possible value of number
Step-by-step explanation:
Let number = n
Given that:
Six times a number is greater than 20 more than that number
It will make the equation like:
6n > 20 + n
Subtracting n from both sides
6n - n > 20 + n - n
5n > 20
Dividing both sides by 5 we get:
5n / 5 > 20/ 5
n > 4
I hope it will help you!
