Answer:
x = 9
Step-by-step explanation:
First step, divide both sides by pi to get rid of it entirely; you should be left with x - 8 = 1 (because when you divide a value by itself, you always get 1, so pi divided by pi gives you 1)
Second step, add 8 to both sides, leaving you with x = 9
Answer:
(2) The motorcycle cost $12,000 when purchased.
Step-by-step explanation:
In the standard exponential equation, y = ab^x, a is the original value.
Since the equation is V(t) = 12,000(0.75)^t, a is 12,000.
This means that the original value was 12,000.
So, the motorcycle cost $12,000 when it was first purchased.
The correct answer is (2) The motorcycle cost $12,000 when purchased.
