Answer:
8.3 (nearest tenth)
Step-by-step explanation:
Hello there!
The answer is B.

-----------------------------------------------------------------------------------------------------
Explanation and Work:We first must identify if the line goes through the origin or not.
The origin is (0, 0)
The line does go through the origin. This means that there is no y-intercept
The specific equation we would you use would be:
y = kx
K is the constant
We find this by finding the slope.
Slope is found by:
y2 = 2
y1 = 0
x2 = 7
x1 = 0
Now, let's plug in these numbers.

So, now let's plug he slope into our formula.
y =

So, our answer would be B.
I hope I helped!

Answer:
8000, 8 on the graph would be your answer
Step-by-step explanation:
as the age goes up the price remains high
Y = cos(x)
sqrt(3)/2 = cos(30º)
dy = -sin(x)*dx
dy = -sin(30º)*(pi/180) = (1/2)*(pi/180)
y + dy = cos(x) - sin(x)dx
y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573
