Wouldn't that be 9 calls then? one minute for each call.
The function given is,

a) Domain
This is the set of all points over which a function is defined.
Therefore, the domain of the function is

b) Solving for the value of a
To solve for the value of a, the value of y = 0 at x = a
Therefore,

Solving for a

Collect like terms

Divide both sides by 3

Hence,
4•1\2=1/16
I don’t know the equation but you can just change it around a little
Answer:
$27
Step-by-step explanation:
Thomas rents a car for his vacation. The mileage include with the rental is 54 miles. For every mile he drives over 54 miles, he needs to pay $1 4/5. If he drives 69 miles, how much extra does he need to pay?
Total mileage included with the rental = 54 miles
Additional cost per mile after 54 miles = $1 4/5
Total miles Thomas drives = 69 miles
Extra miles Thomas drives = 69 miles - 54 miles
= 15 miles
how much extra does he need to pay?
Extra cost Thomas needs to pay = Additional cost per mile after 54 miles * Extra miles Thomas drives
= $1 4/5 * 15 miles
= 9/5 * 15
= (9 * 15) / 5
= 135/5
= 27
Extra cost Thomas needs to pay = $27
