Answer:

(1, 4) and (1,3), because they have the same x-value

Step-by-step explanation:

For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.

In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.

Therefore, the relation is not a function anymore if both ordered pairs are included.

<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>

Rachel Perez rented a car for 3 days at $40.00 per day, plus $0.20 per mile. To protect herself in case of an accident, she purc

expeople1 [14]

Answer:

$290.

Step-by-step explanation:

We have been given that Rachel Perez rented a car for 3 days at $40.00 per day.

$\text{The cost of renting a car for 3 days}=3\times \$40$

$\text{The cost of renting a car for 3 days}=\$120$

We are also told that she pays $0.20 per mile for renting the car. As she covered a total distance of 500 miles, so cost of renting car foe 500 miles will be:

$\text{Cost of renting the car for 500 miles}=500\times \$0.20$

$\text{Cost of renting the car for 500 miles}=\$100$

As Rachel purchased the collision deductible for $10.00 per day to protect herself in case of an accident, so cost of collision deductible for 3 days will be:

$\text{The cost of collision deductible for 3 days}=3\times \$10$

$\text{The cost of collision deductible for 3 days}=\$30$

She also paid $40 for gasoline to cover 500 miles, so we can find total cost to rent the car for 3 days to cover 500 miles by adding all the expenses.

$\text{The total cost to rent the car}=\$120+\$100+\$30+\$40$

$\text{The total cost to rent the car}=\$290$

Therefore, the total cost to rent the car was $290.
