Answer:
160 times
Step-by-step explanation:
Answer:
x+1/x-1 +1 / x+1/x-1 -1= x
Answer:
0 and 2
Step-by-step explanation:

To find zeros set f(x)=0 and solve for x


now factor out x

set each factor =0 and solve for x

no solution for x

zeros of f are 0 and 2
Speed=distance/time
suppose the distance of the first day is d, and the time is t
distance of the second day: d+0.17d=1.17d
time of the second day: t+0.2t=1.2t
speed of the second day: 1.17d/1.2t=0.975(d/t)=(1-0.025)(d/t)
so the speed of the second day is 2.5% slower than the first day.
The factors are 6 and x + 5
