Answer:
![f(1)=-4](https://tex.z-dn.net/?f=f%281%29%3D-4)
Step-by-step explanation:
For finding out
, we have to find the value of y coordinate of the point where its x coordinate is 1.
From the given graph, the point
lies on the graph and has x coordinate as 1.
Drawing a vertical line x=1, it meets the graph at ![(1,-4)](https://tex.z-dn.net/?f=%281%2C-4%29)
Therefore, ![f(1)=-4](https://tex.z-dn.net/?f=f%281%29%3D-4)
She has five dimes and seven nickels with a total of $.85
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

Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.
