Answer:
y = 8x+8
Step-by-step explanation:
We can solve for the function by finding the slope of the linear function using two points. Let's use (0,8) and (1,16)
Slope formula is:
Plug in the 2 points:
Simplify: m = 8
So now, for the equation y = mx+b, we have m which is y = 8x+b
Now we need to find b by using another point from this linear function.
We can use the point (2,24).
Plug this point into the equation y = 8x+b
- 24 = 8(2)+b
- 24 = 16 + b
- b = 8
We have now found the equation of the linear function: y = 8x+8
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 :
Using logarithm properties :
⇒
⇒
≅
The correct option is B. 7.3 years
