Answer:
Step-by-step explanation:
The car uses 15 gallons of gasoline to drive 420 miles.
(15 gal)/(420 mi) = 1/28 gal/mi
The car uses 1/28 gallon of gasoline per mile.
y = mx + b
When x = 0, at the start of the drive, the car has 15 gallons of gasoline.
y = mx + 15
Then for every mile it travels, the amount of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.
The elements of the set S are Tennessee, South Carolina, Florida, and Alabama.
<h3>What is a set?</h3>
A set is a collection of well-defined items or objects.
The items that are found in a set are called the elements of the set.
For example, given a set S, which is the set of states in the U.S. that border Georgia.
The US state Georgia is bordered by Tennessee in the north, South Carolina and the Atlantic Ocean in the east, Florida in the south, and Alabama in the west.
Therefore, the elements of the set S = Tennessee, South Carolina, Florida, and Alabama.
In conclusion, a set consists of well-defined items.

Answer: -12r-12
Step-by-step explanation: There is no equals sign so you can't solve it but you can simplify it. You start out with -3(4r-8)-36. Then, you use PEMDAS. (-3×4r)+(-3×-8)-36. Then, it turns into -12r×+24-36. You just continue to simplify until you can't anymore. You end up with -12r-12.
ANSWER
Option D
EXPLANATION
The parent radical function is
The transformed function is
This is a transformation of the form.
which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.
In this case a=2 and k=3,
there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.
The last choice is correct.
