The best representation of the rate of change of the water remaining with respect to time is -35
<h3>How to determine the best represents the rate of change of the water remaining with respect to time?</h3>
The points on the graph are represented as:
(x, y) = (0, 700) and (20, 0)
The rate of change of the water remaining with respect to time is calculated as
Rate = (y2 - y1)/(x2 - x1)
Substitute the known values in the above equation
Rate =(0 - 700)/(20 - 0)
Evaluate the quotient
Rate = -35
Hence, the best representation of the rate of change of the water remaining with respect to time is -35

The common factor is 4x^2
so factor that out:
4x^2 (1 + 7x) is the fully factored form
Answer:
x = 45, y = 24.
Step-by-step explanation:
If the 2 numbers are x and y:
x + y = 69...........(1)
x = 2y - 3
x - 2y = -3...........(2)
Subtract: (1) - (2):
x - x + y - (-2y) = 69 - (-3)
y + 2y = 72
3y = 72
y = 24.
From equation 1:-
x + 24 = 69
x = 45.
