Answer: (5, 6)
Step-by-step explanation:
The trick to reflect points over the x -axis is (x, y) to (x, -y). In other words, the x value will stay the same and we will change the sign of the y value.
(5, -6) -> (5, 6)
The ordered pair to describe A'A' should be (5, 6).

Answer:
t= 2.52 hours
Step-by-step explanation:
It is given that for first 30 km, the speed of bicyclist is v km/hour
time taken to cover first 30 km is given by
(
)
for next 17 km the speed of bicyclist is 2 km/hour greater than his original speed
so the speed to cover next 17 km = v+2
time taken to cover next 17 km is given by

now total time t spent by the bicyclist to cover entire trip is given by


now if v=18 , we have

now to add fractions we make the denominator same
Hence we will find the LCM of 18 and 20
LCM of 18 and 20 = 180
now we need to make both the denominator equal to 180
