Two cities are 2310 miles apart. a plane leaves one of? them, traveling towards the other at an average speed of 380 miles per hour. at the same time a plane leaves the? other, traveling towards the? first, at an average speed of 390 miles per hour. how long will it take them to? meet?

let H = hours

380H + 390H =2310

770H=2310

2310/770 = 3

H=3 hours

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
