Answer: (x, y) transforms into (-x, y)
Step-by-step explanation:
When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.
So if we do a reflection over the y-axis, then the value of y must be fixed.
So if we start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)
So the rule is, the y value remains equal and the x changes of sign.

Answer:
3.33 meters per second
Step-by-step explanation:
you must find the total time that Mr. B spent to complete the swim and bike.
Information:
0h 25' 10'' ---------> Swim
1h 30' 50'' ---------> Bike
he spent 1h 55' 60'', this is 1h 56'.
now you must substract this time from the record time to find the time alloted to run:
first you convert both times into minutes:
now substracting:
so he must travel 10 km in 50 minutes, that is:
speed = distance/time
1 km is equal to 1000 meters and 1 minute is equal to 60 seconds.
so Mr.B's speed must be 3.33 meters/sec
Answer:
n=80
Step-by-step explanation:
(80-5)+(80-15)=180
75+95=180
180=180
