I'm completely certain it's D.
The x and y values of the original image are being multiplied by two to reach the afterimage coordinates.

Answer:
I don`t know sorry
Step-by-step explanation:
One way, for example, would be the following:
40/11 = 3.63
This handle shows that all students of Mrs. Wilson obtained the same number of points (3.63) to reach 40 points.
Note: there are many ways for 11 students to earn 40 points by making different combinations of notes.
So the formula for an arithmetic sequence (where you're adding or subtracting by the same number each time) is = + d(n - 1)
In this equation:
is the nth term
is the first term
d is the common difference (the number you're adding or subtracting each time)
n is the number of the term (e.g. 1st term, 2nd term, 3rd term etc)
So we're given that = -27, and we can find that d = 15 (because we add 15 each term). We just plug these values into the equation to get...
= -27 + 15 (n - 1)
It looks like that's your answer, D. But if you needed to solve it out further, you could:
We can use the distributive property...
= -27 + 15n - 15
Then combine like terms...
= 15n - 42
