Well...you haven't given any values,but:
When a point is reflected over the y-axis, the signs of the x-coordinates are reversed while the signs of the y-coordinates remain the same.
Example:
Let's say point A is (3,5). When you reflect it over the y-axis, it becomes (-3,5).
Hope this helps!

Step-by-step explanation:
its the only one in its correct multiplication order
For this case we have that the distance that it is necessary to cross to arrive at the lake is of 216 miles.
If the family went there with an average of
To know the time it took me to travel 216 miles, we make a rule of three:
Let "x" be the time spent going to the lake:
48 miles -------------> 1 h
216 miles -----------> x
Thus, to reach the lake they had to travel 4.5 hours.
Now, back home they averaged
To know how much time they used back home, we make a rule of three (to return also travel 216 miles):
Let "y" be the time spent returning home:
54 miles -------------> 1 h
216 miles -----------> y
Thus, the total time is given by:
Answer:
8.5 hours
