Answer:

The correct answers are 8 and 9.

Step-by-step explanation:

To solve an inequality you have to solve it like an equality, but when you obtain the solution you don´t have only one value but a set of values that fit into the solution, in this case, the solution to the inequality is:

$2r\leq 3r-8\\2r+8\leq3r\\8\leq3r-2r\\8\leq r$

The set of values found for the solution of this inequality indicates that r takes values greater than or equal to 8.

Therefore the correct answers are 8 and 9.

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend. "Upon checko

Firdavs [7]

To check how much Tim will pay to refill the gas tank using one of the on-site pumps, we can create a linear model. We know from our problem that the Renter's charge $4.50 per gallon plus a $5.00 refueling, so let $x$ be the number of gallons and $y$ the total cost.
$y=4.50x+5$
We also know that the fuel tank in the car is half empty and the car has a 12-gallon fuel tank, so half tank is 6 gallons. Lets replace the number of gallons in our linear model with 6 to fin the total cost:
 $y=4.50x+5$
$y=4.50(6)+5$
$y=27+5$
$y=32$

Now, to find how much Tim will pay if he decides to refuel the car on his own, we can also create a linear model.
Let $x$ be the number of gallons and $y$ the total cost. We know form our problem that refueling the car on his own will cost $2.59 per gallon and the late fee charge is $32.
 $y=2.59x+32$
We already know that half tank is 6 gallons, so
 $y=2.59(6)+32$
$y=15.54+32$
$y=47.54$

Comparing the result of our two linear models we can conclude that the correct answer is: b. It would be cheaper to return the car on time and pay the refueling costs.
