Answer:
"Absolute value" is the non-negative value of a number, disregarding whether or not it has a sign.
Step-by-step explanation:
"Absolute value" is the non-negative value of a number, disregarding whether or not it has a sign. It can be thought of as how far it is away from the number of 0, whether it's to the left or right. Absolute value of a number is written as |x|, where x = any number. Let's say x was -1. |-1| would be 1 because it's 1 away from 0. If x was just 1, then the number would stay the same.

Answer:
For 2 hours of dog stinting the total cost will be the same for the two services.
Step-by-step explanation:
x to represent the number of hours of dog sitting
<u>Derrick's Dog Sitting </u>
Fixed charged rates = $12
Sitting charges per hour = $7
⇒Charges for x hours siting = x ( Charges per hour)
= x ( $7) = 7x
⇒Total charges of Derrick's Dog Sitting for x hours = Fixed charge + Hourly Rate
= $7x + 12
<u> Darlene's Dog Sitting</u>
Fixed charged rates = $16
Sitting charges per hour = $5
⇒Charges for x hours siting = x ( Charges per hour)
= x ( $5) = 5x
⇒Total charges of Darlene's Dog Sitting<u> </u>for x hours = Fixed charge + Hourly Rate
= $5x + 16
Now, according to the question:
for x hours sitting, both company charges are same.
⇒ $7x + 12 = $5x + 16
or, 7x - 5x = 16 - 12
or, 2x = 4
⇒ x = 2
Hence, for 2 hours of dog stinting the total cost will be the same for the two services.
