You are looking at ratios.
There are 640:460 females to males.
Basically, the males got 460/640ths of 42,000 dollars.
This will take a few seconds with a calculator.
I get $30, 187.50.
Therefore, B. $30,190 wouldbe the closest to the correct answer.
Answer:
Step-by-step explanation:
3/2x-4=20
We simplify the equation to the form, which is simple to understand
3/2x-4=20
We move all terms containing x to the left and all other terms to the right.
+2x=+20+4
We simplify left and right side of the equation.
+2x=+24
We divide both sides of the equation by 2 to get x.
x=12
The vertical asymptote of f(x) is (A) x = 0, –9.

What is a function?</h3>
- A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable).
- Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.
To find the vertical asymptote of f(x):
The vertical asymptotes of a function are the zeroes of the denominator of a rational function
The function is given as:
Set the denominator to 0:
Factor out x:
Express 81 as 9^2:
Express the difference between the two squares:
Split, or or .
Solve for x:
Therefore, the vertical asymptote of f(x) is (A) x = 0, –9.
