4708 - 308 = 4400. You subtract it because the current was 308 more so the last time has to be 308 less.
13 hours
200 divided by 15 = 13.33333333333333
So since this a long number I have to round.
Answer: 13 hours
5 gallons = 170
10 gallons = 340
15 gallons = 510
20 gallons = 680
25 gallons = 850
Answer:
X
Step-by-step explanation:
To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.
To help: draw vertical lines through each graph.
In graph W: the line would pass through the top and bottom of the circle - not a function
In graph X: the line passes once through every area - a function
In graph Y: the line passes through the top curve as well as the bottom curve - not a function
In graph Z: the line passes through the curves multiple times - not a function
