A red and a blue car are 10 miles apart. They are traveling toward one another. The red car is traveling at 45 mph, and the blue car is traveling at a speed v(t). what is the equation for how the distance between them changes as a function of time?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
