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.
I believe the answer would be c. $499.75. If you take (360.75-82.75)/(6-2) you get 278/4 which is dollars/hour, and that =69.5 so the rate of increase is $69.50 per hour, therefore if 6 hours produced $360.75 then you +$69.50•2(hours) and get $499.75
Answer:
28
Step-by-step explanation:
2x + 7 = 4x - 7
14 = 2x
x = 7
BC = 4x = 4(7) = 28
4/5
2(5x+4)=
distribute the 2
10x+8=
subtract 8 from both sides
10x=8
divide 10 from both sides
x=8/10
simplify by 2
x= 4/5
Answer:
10+2x
Step-by-step explanation:
A rectangle has 4 sides. Two pairs of sides are congruent.
For example a rectangle could have sides of 6, 10, 6, and 10.
So the perimeter would be the sum of those sides, 6+6+10+10.
6+6+10+10 can be written like 2(6)+2(10)
For the rectangle in your question it would be 5+5+x+x, which can be written like 2(5)+2(x)
Simplify to 10+2x.
