It is a function because each Input value maps to one output value.
Answer:
The time it took until 2 inches of rain fell is 8 hours
Step-by-step explanation:
You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x
To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:
2= 0.25*x
Solving:

8 = x
So, remembering that the amount of time it had been raining, x, is expressed in hours, <u><em>the time it took until 2 inches of rain fell is 8 hours</em></u>.
Answer:
No solutions
Step-by-step explanation:
First, you need to divide both sides of this equation by -2, making the equation |x-16|=-3. At this point you should know there cannot be any solutions to the equation because absolute value cannot be negative.
3x-7y=2 ; 3x=2+7y x=2x+7y/3
