(4x-5)+(2x-3)
4x+2x= 6x
-5+-3= -8
6x-8
The function of the relationship above is y=5x+4
Bill and Amy travel the same distance from home to school of 14.4 kilometers. Amy takes 40 minutes of time to arrive to school which means she has a rate of 14.4 km /40 minutes or 6 meters/ second. Bill takes a total 60 minutes to arrive to school. Hence Bill's rate is equal to 14.4 km/60 minutes or 4 meters/ second.Amy's is 2 m/s faster than Bill's speed, then.
25-5x=5(-x+5)
25-5x=-5x+25
-5x+5x= 25-25
0=0
So the answer will be A: there is no solution
