I think what you would do is subtract the "salvage value" of 4,000 from 22,000 to get 18,000. Then since you need the number of years, you would divide 22,000 by the depreciation price of 3,600 to get 5. It would take 5 years for the car's value to reach 4000, therefore she would want to sell it before then.
Answer:
-2x+5
Step-by-step explanation:
slope= -2/1 or -2
y-intercept= 5
For this one I usually put the functions over one another like if it was an addition problem
Answer:
Terms:
1) = 7/3
2) = -7/9
3) = 7/27
4) = -7/81
Step-by-step explanation:
Your question did not state the equation of f(x), however; assuming f(x) = 7/(1+x) ,....... at a = 2
see solution attached then use it to work your f(x)
