Solve the application by using a system of linear inequalities in two variables.The equation that represents the proper traffic control and emergency vehicle response availability in a small city is
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
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
