B. y = 10x + 680
<span>Breakdown: </span>
<span>he bring a total of $830 home </span>
<span>he opens 15 accounts at $10/account </span>
<span>he has an unknown amount of salary. </span>
<span>Hence to determine the salary, Subtract the commission of the opened accounts from the total he brings home i.e. </span>
<span>830 = Salary + Commission (rearranging gives) </span>
<span>Salary = 830 - Commission (but Commission = 15*10 = 150) </span>
<span>Salary = 830 - 150 = 680 </span>
<span>Therefore his pay structure is of the form </span>
<span>Y = 680 + 10x, where x is the number of accounts opened </span>
<span>Hope that helps</span>
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.
