(7x+2)° = (9x–8)°

=>7x –9x = –8–2

=> –2x = –10

=> x = 10/2

=> x = 5

<ADB = (7x+2)°

= 7×5+2

= 37°

<BDC = (9x–8)°

= 9×5–8

= 45 –8

= 37°

<ADC = 37° + 37°

= 74°

Mr. Keller bought a car for $20,000. A study shows that a car will depreciate (go DOWN in value) by 15% each year. How much is M
Schach [20]
A: the formula would be f(x) = P(R) ^T or f(x) = Principle(rate)^time

B: f(x) = 20,000(0.85)^5  

C: = 8,874.10625

D: Yes, the final answer makes sense compared to the origional cost of the car in relation to the formula. As well, time decreases the value of a car, so for the cost to be so low only makes sense due to the cars decrease in value or an extended and elongated amount of time. 

E: You can solve this equation graphically by plotting th point at 20,000 and then taking 85% of 20,000 and plotting it each time until you get to the fifth year.
