Answer: 45,000.
Step-by-step explanation:
The equation of inverse variation is given by:-

, where k is the constant of proportionality.
Given: After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.
Here,

Then, 
or
[answer is same in both cases.]
Hence, the constant of proportionality in this inverse variation is 45,000.
Answer:
x = 1/2, −1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Step-by-step explanation:
<u>Break down the word expression:</u>
The sum of 5 and b divided by two
the sum (+) of 5 and b (5 + b) divided by 2.
<u>Expression:</u>

Parentheses represent that we need to add first, in order to divide the sum by 2.
