x = 0 is a vertical line.

If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

The answer is (-3,4) because mirrored give you -3 and then mirror the -4 and you get just 4

A swimming pool holds 250,000 gallons of water and is being drained at 200 gallons per minute. How many gallons remain in the pool after 5 minutes than after 20 minutes?

Answers

Answer:

After 5 minutes, the pool will hold 249,00 gallons of water.

After 20 minutes, the pool will hold 246,000 gallons of water.

After 5 minutes the pool will have 249,000 gallons since 5x200=1000 and 250,000-1000=249,000.
After 20 minutes it will be at 246,000 gallons since 20x200=4000 and 250,000-4000= 246,000.
