Answer: x= -0.2
Step-by-step explanation:
Answer:
∠BAC = 105°
Step-by-step explanation:
2(5x) = 9x+21
10x = 9x+21
reduce:
x = 21
∠BAC = 5x = 105°
Answer:
60
Step-by-step explanation:
Answer:
- After 17 years and 3 months
Step-by-step explanation:
<u>Given function:</u>
We are looking for the value of x at f(x) < 2000
<u>Solve the equation:</u>
- 2000 = 18000(0.88)^x
- (0.88)^x = 2000/18000
- (0.88)^x = 0.1111
- log (0.88)^x = log 0.1111
- x = log 0.1111 / log 0.88
- x = 17.18
After 17 years and 3 months the car value drops below $2,000
