A 1 2/3
-4 1/3 / -2 3/5=1.6666=1 2/3
$20 because 10% of 40 is 10 and the price now is 40 so 2 years before would have been 20
Answer:

Step-by-step explanation:
To find the equation of this circle, we must know the center and the radius.
We can find the radius by dividing the value of the distance formula by 2 (since
):

We can then find the center of the circle by averaging the coordinates:


Then, we substitute these values into the equation of a circle:
