By the way, I'm doing the same exam for Geometry as well. There's a lot of proof questions on there which I'm not good at doing for the reasoning part. If you finish the exam before I do, maybe you can message me what the answers are for some of the questions on there so I know if my answers for the questions are incorrect or not.
Besides that, hope the answer above is correct for you.

The equivalent equation is d=17+12.5
it simplifies to d=29.5
Answer:
19
Step-by-step explanation:
Answer:
B. 7.3 years
Step-by-step explanation:
The question is wrong. The correct function is :
We have the function 
that represents the value of a piece of farm equipment after 
years.
This means that when 
its original value is :
Now we want to calculate approximately when will its value be half its original value. Then, we write :
is half of its original value. We need to find that satisfies the following equation :
Solving for :
⇒
Now we apply natural logarithm to each side of the equation :
![ln(0.5)=ln[(0.91)^{x}]](https://tex.z-dn.net/?f=ln%280.5%29%3Dln%5B%280.91%29%5E%7Bx%7D%5D)
Using logarithm properties :
⇒
![ln(0.5)=x[ln(0.91)]](https://tex.z-dn.net/?f=ln%280.5%29%3Dx%5Bln%280.91%29%5D)
⇒
≅ 
The correct option is B. 7.3 years
