What is a rational function?
In mathematics, a rational function is any function that can be described by using a rational fraction, which is an algebraic fraction such that each the numerator and the denominator are polynomials. The coefficients of the polynomials need no longer be rational numbers; they'll be taken in any field k.
A rational function is one that can be written as a polynomial divided by a polynomial. for the reason that polynomials are defined everywhere, the domain of a rational feature is the set of all numbers except the zeros of the denominator. example 1. f(x) = x / (x - 3). The denominator has only one 0, x = 3.

if you are advanced.you can see the relationship between the first triangle and the second triangle.
but if you are not advance in geometry.you can compare the side that are relative to one another.
side Ac relative to side zx
side Bc relative to side yx
and
side Ab relative to side zy
The corresponding sides as equal ratios will be AB / YZ = BC / YZ = AC / XZ. Then the correct option is D.

solve for y:
x^3 + (1/a)y= xy+9
Step-by-step explanation:
[tex] {x}^{3} + ( \frac{1}{a} )y = xy + 9[/tex]
[tex]x {}^{3} + \frac{y}{ay} = xy + 9[/tex]
[tex]x {}^{3 } = xy + 9 - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = xy - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = y(x - \frac{1}{a} )[/tex]
Divide both sides by x-1/a
[tex] \frac{x {}^{3} - 9}{x - \frac{1}{a} } = y[/tex]

Find the value of x and
y if x-y=3 and 2x+3y=4
Answer:
Step-by-step explanation:
Given :
x-y = 3 equation(i)
2x + 3y = 4 equation(ii)
Now,
x - y = 3
x = 3 + y
substitute the value of x in equation (ii)
2x + 3y = 4
2(3 + y) + 3y = 4
6 + 2y + 3y = 4
6 + 5y = 4
y = -2/5
The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?
9514 1404 393
Answer:
1125
Step-by-step explanation:
The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.
$5.60n = $6300
n = 6300/5.6 = 1125
The company should sell 1125 units per month to break even.
