Answer:
The value at the end of year 2 is $4400.
Step-by-step explanation:
The best approach here is to determine the expression for the line depreciation and then calculate the depreciation value at x = 2 years.
A line is given by
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
where m is the slope and b the bias (aka y-intercept). You can determine both directly from what is given. The slope is change in y divided by change in x. We know that over 5 years the car loses (500-7000)=-6500 in value. So, the slope is m=-6500/5 (note the negative sign). At time 0, the y-intercept is 7000, since that is the initial value (at year 0). So our line function is fully identified:
![y = -\frac{6500}{5}x+7000](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B6500%7D%7B5%7Dx%2B7000)
and gives you the value of the car in any given year. To answer the question, we now plug in 2 as value of x:
![y=-\frac{6500}{5}\cdot 2 + 7000= 4400](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B6500%7D%7B5%7D%5Ccdot%202%20%2B%207000%3D%204400)
<h3>
Answer: C) 75% increase</h3>
===========================================================
Explanation:
We go up by 300,000 since 700,000-400,000 = 300,000
Divide this increase by the original amount
(300,000)/(400,000) = 0.75 = 75%
Therefore, we have a 75% increase.
It might help to ignore the zeros and just think of it like this: "We start at 4 and jump to 7. That's an increase of 3, so we have a 3/4 = 0.75 = 75% increase".
Answer:
x=8
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
16 = 1/2 (4) x
16 =2x
Divide each side by 2
16/2 = 2x/2
8 =x
The height is 8 units
6 and 2/8 is correct hope this helps.
