First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer.
To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)
8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120.
120/4=30
It takes 30 minutes to fill the pool up to 120 gallons.
The answer is B because you have to look at all the numbers and find the only one that matches the graph
Answer:
there are no real solutions
Step-by-step explanation:
The discriminant is (-10)² - 4*6*50 is below zero, hence there are no solutions.
