Find an equation in standard form for the hyperbola with vertices at (0, ±8) and asymptotes at y = ±4 divided by 3.x.

a. y squared over 9 minus x squared over 16 = 1
b. y squared over 36 minus x squared over 64 = 1
c. y squared over 64 minus x squared over 9 = 1
d. y squared over 64 minus x squared over 36 = 1

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi
