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.

<u>Answer:</u>
Total paid = $717.3
Finance charge = $167.3
<u>Step-by-step explanation:</u>
The cost price of mountain bike = $550
The down payment on bike = 75% of $550 = 0.75 * 550 = $412.5
We know that he will make 12 payments of $25.40 each so total monthly payments = 12 * 25.40 = $304.8
The total amount paid = Down payment + Total monthly payments = $412.5 + $304.8 = $717.3
The finance charge = Total amount paid - Cost price = $717.3 - $550 = $167.3

Answer:
A.60=(x+45)
Step-by-step explanation:
these are Alternate angles therefore, 60=(x+45)
x=60-45
x=15
the two angles are equal in alternate angles =x+45
= 15+45
=60
