Let x be the number of days and y represent miles driven.
Since it costs 25 per day, you multiply 25 by x.
25x
10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y
25x+.1y
The answer is <span>a.) 25x + 0.1y</span>.
Umm i would say a
hope i helped
Answer:
y = 20.922
Step-by-step explanation:
Simply plug in <em>x</em> and evaluate:
y = 15 + 3ln(7.2)
Only way to calculate ln is to plug into a calc:
We should get 20.9222 as our answer.
Answer:
Step-by-step explanation:
5h-8=2h+19
5h-2h=19+8
3h=27
h=27/3
h=9
Answer: The correct answer is Choice D.
This is an example of an exponential equation. They are in the form of y=ab^x, where a is the starting value, b is the rate and x is the number of years.
Our data starts at 2500 and increases by 5%, or 100% + 5% = 1.05.
If you put them together, you have the equation y = 2500(1.05)^x, Choice D.
