Answer:
f(x)=2000-8x
Step-by-step explanation:
2000 is initial amount that gets subtracted
8x is the amount of gallons being siphoned out, where x is t, or minutes.
f(x) = 10x -5 and g(x) = (x+5)/10 are inverses of each other , Option D is the correct answer.
<h3>What is a Function ?</h3>
A function is a mathematical statement which relates two variables , a dependent and an independent variable.
The inverse of a function is found by replacing every y by x and vice versa , and then solve for y
The equation
f(x) = 4/x - 3
or
y= 4/x -3
Replacing y by x
x = 4/y -3
x +3 = 4/y
y = 4/(x+3)
Which do not correlate with the given inverse
f(x) = 10x -5
y = 10x -5
for finding inverse
10y -5 = x
10y = x+5
y = (x+5)/10
g(x) = (x+5)/10
Therefore , Option D is the correct answer.

Answer:
C=2v
Step-by-step explanation:
because 0*2=0 1*2=2 2*2=4 3*2=6 4*2=8 5*2=10 so C=2v
