For the function
f(x) = x + 10/6x + 4, consider the following.
(a)Find the vertical and horizontal asymptotes for the graph of f.
Vertical:
Horizontal:
b)Find f^ −1.
f^ −1(x) =
c)Find the vertical and horizontal asymptotes for the graph of
f^ −1
Vertical:
Horizontal:
Show all steps.
Using the concepts of asymptotes and inverse function, we have that:
a) For f, the vertical asymptote is x = -2/3 and the horizontal asymptote is y = 1/6.
b) The inverse function is: [tex]y = f^{-1}(x) = \frac{4x - 10}{1 - 6x}[/tex]
c) For the inverse function, the vertical asymptote is x = 1/6 and the horizontal asymptote is y = -2/3.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.For this problem, the function is given by:
[tex]f(x) = \frac{x + 10}{6x + 4}[/tex]
The zero of the denominator is:
6x + 4 = 0
6x = -4
x = -4/6 = -2/3.
Hence the vertical asymptote is x = -2/3.
The horizontal asymptote is given as follows:
[tex]y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{x + 10}{6x + 4} = \lim_{x \rightarrow \infty} \frac{x}{6x} = \lim_{x \rightarrow \infty} \frac{1}{6} = \frac{1}{6}[/tex]
How to find the inverse function?To find the inverse function of a function y = f(x), we exchange x and y then isolate y.
Exchanging x and y, we have that:
[tex]x = \frac{y + 10}{6y + 4}[/tex]
Applying cross multiplication:
x(6y + 4) = y + 10
6xy - y = 10 - 4x
y - 6xy = 4x - 10
y(1 - 6x) = 4x - 10
[tex]y = f^{-1}(x) = \frac{4x - 10}{1 - 6x}[/tex]
Applying the same procedure, for the inverse function, the vertical asymptote is x = 1/6 and the horizontal asymptote is y = -2/3.

[tex] \rm \int_{0}^1 \int_{0}^1x \bigg \{ \frac{1}{1 - xy} \bigg \}dydx \\ [/tex]
The fractional part vanishes when the argument is an integer; in this case, for
[tex]\left\{\dfrac1{1-xy}\right\} = 0 \iff \dfrac1{1-xy} = n \iff xy = \dfrac{n-1}n[/tex]
which are hyperbolas in the [tex](x,y)[/tex]-plane.
Observe that between neighboring hyperbolas, we have
[tex]\dfrac{n-1}n < xy < \dfrac n{n+1} \\\\ ~~~~ \implies \dfrac1{n+1} < 1-xy < \dfrac1n \\\\ ~~~~ \implies n < \dfrac1{1-xy} < n+1 \\\\ ~~~~ \implies \left\{\dfrac1{1-xy}\right\} = \dfrac1{1-xy} - \left\lfloor\dfrac1{1-xy}\right\rfloor = \dfrac1{1-xy} - n[/tex]
Split up the integral over [tex][0,1)^2[/tex] along the curves [tex]xy=\frac{n-1}n[/tex]. The subregions somewhat resemble the layers or scales of an onion (see attached plot with the first 5 "scales").
Let [tex]S_n[/tex] denote the [tex]n[/tex]-th ([tex]n\in\Bbb N[/tex]) "scale", starting from the blue region closest to the origin and counting diagonally upward in the direction of (1, 1).
In Cartesian coordinates, the integral over [tex]n[/tex]-th "scale" is
[tex]\displaystyle \iint_{S_n} x \left(\frac1{1-xy} - n\right) \, dy \, dx \\\\\\ ~~~~~~~~= \int_{(n-1)/n}^{n/(n+1)} \int_{(n-1)/(nx)}^1 x \left(\frac1{1-xy} - n\right) \, dy dx \\\\\\ ~~~~~~~~~~~~~ + \int_{n/(n+1)}^1 \int_{(n-1)/(nx)}^{n/((n+1)x)} x \left(\frac1{1-xy} - n\right) \, dx[/tex]
(see attached plot of the 2nd "scale" for reference)
The integral is trivial, so I'll leave it to you to confirm that it drastically reduces to
[tex]\displaystyle \iint_{S_n} x \left(\frac1{1-xy} - n\right) \, dy \, dx = \frac1{2n (n+1)^2} = \frac12 \left(\frac1n - \frac1{n+1} - \frac1{(n+1)^2}\right)[/tex]
Now we recover the original integral by summing over [tex]\Bbb N[/tex].
[tex]\displaystyle \int_0^1 \int_0^1 x \left\{\frac1{1-xy}\right\} \, dy \, dx = \frac12 \sum_{n=1}^\infty \left(\frac1n - \frac1{n+1} - \frac1{(n+1)^2}\right) \\\\ ~~~~~~~~ = \frac12 \left(\left(1-\frac12\right)+\left(\frac12-\frac13\right)+\left(\frac13-\frac14\right)+\cdots\right) - \frac12 \sum_{n=2}^\infty \frac1{n^2} \\\\ ~~~~~~~~ = \frac12 - \frac12 \left(\sum_{n=1}^\infty \frac1{n^2} - 1\right) \\\\ ~~~~~~~~ = \frac12 - \frac12 \left(\frac{\pi^2}6 - 1\right) = \boxed{1 - \frac{\pi^2}{12}}[/tex]

Solve the system by back substitution.
-2x - 4y - z - 3w = -5
y + 6z + 2w = 8
4z + 4w = 8
-4w = -12
Solution should be set like {( _ , _ , _ , _ )}
Answer:
w = 3, x = -35/2, y = 8, z = -1
Step-by-step explanation:
Solve the following system:
{-3 w - 2 x - 4 y - z = -5
{2 w + y + 6 z = 8
{4 z + 4 w = 8
{-4 w = -12
In the fourth equation, look to solve for w:
{-3 w - 2 x - 4 y - z = -5
{2 w + y + 6 z = 8
{4 z + 4 w = 8
{-4 w = -12
Divide both sides by -4:
{-3 w - 2 x - 4 y - z = -5
{2 w + y + 6 z = 8
{4 z + 4 w = 8
{w = 3
Substitute w = 3 into the first, second, and third equations:
{-9 - 2 x - 4 y - z = -5
{6 z + y + 6 = 8
{4 z + 12 = 8
{w = 3
In the third equation, look to solve for z:
{-9 - 2 x - 4 y - z = -5
{6 z + y + 6 = 8
{4 z + 12 = 8
{w = 3
Subtract 12 from both sides:
{-9 - 2 x - 4 y - z = -5
{6 z + y + 6 = 8
{4 z = -4
{w = 3
Divide both sides by 4:
{-9 - 2 x - 4 y - z = -5
{6 z + y + 6 = 8
{z = -1
{w = 3
Substitute z = -1 into the first and second equations:
{-4 y - 2 x - 8 = -5
{y = 8
{z = -1
{w = 3
Substitute y = 8 into the first equation:
{-2 x - 40 = -5
{y = 8
{z = -1
{w = 3
In the first equation, look to solve for x:
{-2 x - 40 = -5
{y = 8
{z = -1
{w = 3
Add 40 to both sides:
{-2 x = 35
{y = 8
{z = -1
{w = 3
Divide both sides by -2:
{x = -35/2
{y = 8
{z = -1
{w = 3

The vertices of a figure are given. What are the coordinates of the image after the given dilation? Identify the type of dilation?
Q (-3,0), R (-3,6), T (4,6), U (4,0)
k=1/3
The new images has vertices Q´(-1, 0), R´(-1, 2), T´(4/3, 2), U´(4/3, 0) and the type of dilation is contraction.
When we dilate the points of a given figure, we simply multiply each x-coordinate and y-coordinate by the scale factor.
Here the points are Q (-3,0), R (-3,6), T (4,6), U (4,0) and the scale factor is
k = 1/3
Therefore,
⇒ Q (-3,0) → Q´ (-3 × 1/3,0 × 1/3) = (-1, 0)
⇒ R (-3,6) → R´ (-3 × 1/3, 6 × 1/3) = (-1, 2)
⇒ T (4,6) → T´ (4 × 1/3, 6 × 1/3) = (4/3, 2)
⇒ U (4,0) → U´ (4 × 1/3, 0 × 1/3) = (4/3, 0)
Thus, the new images has vertices Q´(-1, 0), R´(-1, 2), T´(4/3, 2), U´(4/3, 0) and the type of dilation is contraction
What is dilation?
Dilation is the process of modifying the dimensions of an object or shape by varying some scale variables. For instance, a circle with a radius of 10 units gets shrunk to a circle with a radius of 5 units. This technique is applied in photography, fine art, logo design, and other fields.

a. one solution: (8,0)
b. one solution: (0,8)
c. no solution
d. infinite number of solutions
The linear system of equation has one solution as x = 16 and y = -12.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
The given system of equation are :
y=-x+4..........(1)
x + 2y = -8......(2)
Now, solving the above using substitution of y in equation (2) :
x + 2y = -8
x+2(-x+4) = -8
x-2x+8 = -8
-x = -16
x = 16
Now, substituting back x value in equation (1) we get :
y = -x+4
y = -16 +4
y = -12
Therefore, The linear system of equation has one solution as x = 16 and y = -12.

5 1/2 x 1 1/4
put in simplest form
Answer:
6 7/8
Step-by-step explanation:
First we would need to turn the 5 1/2 into a improper fraction. Then, do the same for the 1 1/4 as well. To do this, multiply the denominator by the whole number and then add the numerator. Once you get those values, you simply multiply across, meaning the numerators get multiplied together and the denominators get multiplied together. The value you get is the improper fraction form of the simplest form. Then you can convert it back to a mixed fraction if that is the form you need. To do this divide the numerator by the denominator. Now we have a value of 11/2 x 5/4 = 55/8. So divide 55 by 8 and leave the remainder in fraction form. Therefore the answer should be 6 7/8, after it is reduced.

Given the graphs of f(x) and g(z) below, find the composition of functions f(g(-1)).
The composition of the functions, f(g(-1)) = 2.
How to Find the Composition of Functions?To find the composition of the functions, f(g(-1)), first, find the function, g(-1) by tracing the value of y that will give an x-value of -1 on the function graph.
The next step is to use the value you get in the first step to trace which value of y will give an x-value equivalent to what you got in the first step on the second function graph.
Thus, from the graph of g(x), g(-1) = 0. Using the graph of f(x), the value of y when x = 0 is 2.

The sum of three consecutive odd numbers is 177. Find the number. Step by step please
Answer:
57, 59 and 61
Step-by-step explanation:
Let the first odd number be n The next consecutive odd number is n + 2 and the next one after that is n + 4
(consecutive odd numbers have difference of 2 between them. For example if 7 is the first odd number next one is 9(7+2) and the next one is 11(7+4)
We are given that the sum of the numbers is 177. So we have the following equation:
n + (n + 2) + (n +4) = 177
Simplifying gives
n + n + 2 + n + 4 = 177
Collect like terms:
n + n + n + 2 + 4 = 177
3n + 6 = 177
Subtract 6 from both sides
==> 3n = 177 - 6
==> 3n = 171
Divide by 3 both sides
3n/3 = 171/3
n = 57 and this is the first of the odd numbers
The next odd number is 57+ 2 = 59
and the next one after that is 59 + 2 = 61 (same as 57 + 4)
The store is selling lemons at $0.65 each. Each lemon yields about 2 tablespoons of juice. How much
will it cost to buy enough lemons to make two 9-inch lemon pies, each requiring half a cup of lemon
juice?
The cost of buying lemons to make two 9-inch lemon pies is $5.20.
What is the total cost?The first step is to convert cup to tablespoons
1 cup = 16 tablespoons
one 9-inch lemon pie would require 8 tablespoons (16 /2)
two 9-inch lemon pie would require 16 tablespoons (8 x 2)
The second step is to determine how much lemons would be needed.
Lemons needed = table spoons needed / table spoon one lemon would yield
