Answer:
20x+50
Step-by-step explanation:
Let x represent the number of days he has the car
20x+50
It is 20x, because it costs 20 dollars for each day he has the car, and +50, because there is a fee, regardless of how many days he has the car.

Answer:
$5.16
Explanation:
Okay, so the first step is to move the decimal point of the 72% over to the left twice. Since it is a whole number, the decimal is at the back. So, the number went from 72 to .72.
After that, multiply 3.00 by .72 Like this:
3.00 * .72 = 2.16
The last step is to add the original number to that number. Like this:
3.00 + 2.16 = 5.16
Hope this helps !
Answer:
1. You can tell because every y value divided by its corresponding 3 value is 1/3, except 0 because 0 divided by 0 is 0.
2. Samuel is incorrect because when his sister's age is divided by his age, it differs every year.
(Example: 5/10 ≠ 10/15)
Short answer: you don't.
The linear term in the numerator of the integral means the form shown is not applicable. Rather, you perform the integration using partial fraction expansion.

The integral is ...
... (1/35)ln|5x-1| +(6/35)ln|5x+13| +C
_____
If the numerator of your integral were a constant, then the fractions multiplying the separate partial fraction integrals would have the same magnitude and opposite signs. You would end with the difference of logarithms, which could be expressed as the log of a ratio as shown in your problem statement.
