A new car is purchased for $17,000 and over time its value depreciates by one half every 3 years. What is the value of the car 1
9 years after it was purchased, to the nearest hundred dollars?

Answer:
200
Step-by-step explanation:
Halving Formula:
y=a\left(\frac{1}{2}\right)^{\frac{t}{h}}
y=a(
2
1
)
h
t
a=17000\hspace{40px}h=3\hspace{40px}t=19
a=17000h=3t=19
h is the halving time
\text{Plug in:}
Plug in:
y=17000\left(\frac{1}{2}\right)^{\frac{19}{3}}
y=17000(
2
1
)
3
19
y=210.826702215
y=210.826702215
y\approx 200
y≈200
Answer:
The answer is "$238".
Step-by-step explanation:
Current worth
depreciates by
in 3 years.
time= 19 years
depreciates rate=?
Using formula:


calculates depreciate value in 3 year 

so,


depreciates rate= 20%

Not 100% sure that this is correct but, hope this helps! :) If you have any questions than ask me.
Find the slope
m= -5-6 / -8-(-2)
m= -11/-6
m=11/6
Use slope and point to create equation
y-6= 11/6(x-(-2))
y-6=11/6x+22/6
y=11/6x+58/6
y=11/6x+29/3
Change to standard form
Standard form: ax + by = c
-11/6x+y=29/3
