The answer is (-1,-2)

First, we put the equation in standard form
Add the 2x to the other side leaving us with -y = 2x +4. They y must be positive so we multiply the whole equation by -1. This gives us y = -2x - 4. We then plug the coordinates in to find out which one comes out to be true.

The only one that comes out true is (-1,-2)
-2 = -2(-1) - 4 which comes out to -2 = -2 True.

7.29. hose fills a swimming pool at a rate of 0.5 gallons per second. If the pool's capacity is 9,000 gallons, then how many hou
Bond [772]

Answer:

<u>It takes the hose 300 hours to fill the pool</u>

<u />

Step-by-step explanation:

The hose can fill the pool at a rate of 0.5 gallons per second, which means that it can fill the pool at a rate of 1 gallon per 2 seconds. It needs to fill 9000 gallons of water, so assuming the ratio remains 1:2, it takes the hose 18000 (9000*2) seconds to fill the pool completely.

However, it is important to note that we have to answer in terms of hours. There are 60 seconds in an hour, so 18000 seconds is equal to <u>300 hours</u> (18000/60).
