Answer:
Rate of change is 6/7 Initial value: 6
Step-by-step explanation:
To find the slope (which is the rate of change), use (y1 - y2)/(x1 - x2).
x1 and y1 will be (0, 6)
x2 and y2 will be (7, 0)
Note that x1 x2 y1 y2 can be any points on the line, I just chose these because they were x and y-intercepts.
(6 - 0)/(0 - 7) = 6/7
The initial value is simply the y-intercept, which is 6.
Answer:
Step-by-step explanation:
Given
Rate of Long family's sprinkler is 25 L/hr
rate of Harris family's sprinkler is 35 L/hr
Total time for which sprinkler is used =55 hr
Let long family run their sprinkler for x hr
therefore Harris family time=55-x
Total volume collected=1625 L
thus

25x+1925-35x=1625
1925-1625=10x
300=10x
x=30 hr
long family used for 30 hr and Harris family used for 20 hr
