value. If the leading coefficient is negative, the graph has a
value.

In the equations, a and b represent the price per night for a room in hotel a and hotel b, respectively, w weeks after september 1 last autumn. what was the price per night in hotel a when it was equal to the price per night in hotel b? a = 240 − 20w b = 320 − 30w

What could explain what happened when the time was equal to 120 minutes
