Answer:
4n=y
Step-by-step explanation:
because 4 is the number of characters they use and n is the number of spaces or characters it takes
N+4=13
-4 -4
n = 9
the sum of a number(n) and 4 that is no larger than 13 is 9
Step-by-step explanation:

This is the equation of the ellipse. Since the denominator is greater for the y values, we have a vertical ellipse. Remember a>b, so a
The formula for the foci of the vertical ellipse is
(h,k+c) and (h,k-c).
where c is
Our center (h,k) is (2, -5)

Here a^2 is 9, b^2 is 4.



So our foci is

and

Answer:
Step-by-step explanation:
im pretty sure it is 768/187.5 = about 4
because you are taking the highest number and putting it over the lowest number
