A bus makes a stop at 2:30, letting off 15 people and letting on 9. The bus makes another stop ten minutes later to let off 4 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?

The original number of passengers on the bus decreased by 10 after the second stop.

Step-by-step explanation:

at 2:30:

15 passengers got off and 9 got on.

This means that the number of passengers = x - 15 + 9 ;number of passengers = x -6

10 minutes later:

4 passengers got off the bus

This means that the number of passengers = (x-6) - 4 ;number of passengers = x - 10

The original number of passengers on the bus decreased by 10 after the second stop

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
