Use Mathematical Models Involving Linear Inequalities
-The equation that represents the proper traffic control and emergency vehicle response availability in a small city is 2P + 3F ≤ 23, where P is the number of police cars on active duty and F is the number of fire trucks that have left the firehouse in response to a call. In order to comply with staffing limitations, the equation 2P + F ≤ 17 is appropriate. The number of police cars on active duty and the number of fire trucks that have left the firehouse in response to a call cannot be negative, so P ≥ 0 and F ≥ 0. Graph the regions satisfying all the availability and staffing requirements, using the horizontal axis for P and the vertical axis for F. If 3 police cars are on active duty and 6 fire trucks have left the firehouse in response to a call, are all of the requirements satisfied?

A) No


B) Yes

C) No

D) Yes
