= a(x + y) + 3b(x + y)
Finally, group the common factors of x + y and collect the terms to get:
(x + y )(a + 3b)
The factors of the given expression are (x + y ) and (a + 3b).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have been given that expression as :
ax + ay + 3bx + 3by
We have to factorize the given expression.
⇒ ax + ay + 3bx + 3by
Factor like terms.
⇒ (ax + ay) + (3bx + 3by)
⇒ a(x + y) + 3b(x + y)

The manufacturer's suggested retail price (MSRP) for a particular car is $25,425, and it is expected to be
worth $11,730 in 5 years.
(a) Find a linear depreciation function for this car.
(b) Estimate the value of the car 7 years from now.
(c) At what rate is the car depreciating?
(a) What is the linear depreciation function for this car?
(Simplify your answer. Do not include the $ symbol in your answer.)
Answer:
(a) The linear depreciation function of the car which gives the worth of the car y after a number of years, t is given as follows;
y = 25,425 - 2,739 × t
(b) The value of the car 7 years from now is $6,252
(c) $2,739 per year
Step-by-step explanation:
The manufacture's suggested retail price (MSRP) for the car = $25,425
The amount the car is expected to be worth in 5 years = $11,730
(a) The linear depreciation is given as follows;
[tex]Depreciation \ Per \ Year \ = \dfrac{Cost \ of \, Asset - Salvage \ Value}{Life \ of \, Asset \ in \ use}[/tex]
Where;
Cost of Asset = $25,425
Salvage Value = $11,730
Life of Asset in use = 5 years
We get;
[tex]Depreciation \ Per \ Year \ = \dfrac{\$ 25,425 - \$11,730}{5} = \$2,739/year[/tex]
Therefore, the linear depreciation function, can be written as follows;
y - 25,425 = -2,739×(t - 0)
y = -2,739·t + 0 + 25,425 = 25,425 -2,739·t
y = 25,425 - 2,739 × t
Where;
y = The expected worth of the car after a given number of years
t = The number of years used for the calculation of the depreciation
(b) The value of the car 7 years from now is given by substitution as follows;
Whet t = 7, we have;
y = 25,425 -2,739·t = y = 25,425 -2,739 × 7 = $6,252
The value of the car 7 years from now = $6,252
(c) [tex]Depreciation \ Per \ Year \ = \dfrac{\$ 25,425 - \$11,730}{5} = \$2,739/year[/tex]
The car is depreciating at a rate of $2,739 per year.

The simplified expression for g(f(x)) is 2x.
The simplified expression for g(f(x)) is x.

The functions are not inverses of each other.
Answer: 1,4,5
Step-by-step explanation:
The correct options are, The simplified expression for g(f(x)) is x.
The functions are not inverses of each other.
What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
Given, f(x) = 1/(8x³).
f(x) = 1/(2x)³.
y = 1/(2x)³.
(2x)³ = 1/y.
[tex]2x = \frac{1}{y^\frac{1}{3}}[/tex].
[tex]x = \frac{1}{2y^\frac{1}{3}}[/tex].
[tex]f^{-1}(x) = \frac{1}{2x^\frac{1}{3}}[/tex] and g(x) = [tex]2x^\frac{1}{3}[/tex] so, they are not inverses of each other.
Now, f(g(x)) = [tex]\frac{1}{8((2x)^\frac{1}{3})^3}[/tex].
f(g(x)) = 1/16x.
g(f(x)) = [tex]2(1/8x^3)^\frac{1}{3}[/tex].
g(f(x)) = x

Martha tiene un negocio en el cual vende huevos empacados por docena. Uno de sus clientes le pide solamente 5/6 de docena, ¿cuántos huevos debe venderle Martha?
Answer:
María solamente debe venderle al cliente 10 unidades
Step-by-step explanation:
Explicación paso a paso:
Una docena representa un total de doce (12) unidades. Los huevos se empacan por docena, por lo tanto si nos piden solo 5/6 de la docena, multiplicamos dicha fracción por 12 unidades:
5/6 · 12 = (12 · 5)/6 = 60/6 = 10 unidades
Por lo tanto, María solamente debe venderle al cliente 10 unidades, es decir 5/6 representa 10 unidades de los huevos
Usando conceptos de proporción, se encuentra que Martha debe vender 10 huevos al cliente.
---------------------------
Esta pregunta se resuelve por proporciones, usando una regla de tres.Una docena está compuesta por 12 huevos. ¿cuántos huevos en 5/6 de docena?1 docena - 12 huevos
5/6 de docena - x huevos
Aplicando multiplicación cruzada:
[tex]x = 12 \times \frac{5}{6} = \frac{12 \times 5}{6} = 2 \times 5 = 10[/tex]
Martha debe vender 10 huevos.

Use the diagram to the right a. What algebraic expression represents GK? b. If GK = 24. what are GH and JK? G H J K a What algebraic expression represents GK? GK (Simplify your answer Do not factor)
Answer:
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached below;
From the diagram GK = GH+HJ+JK
Given GH = GJ-HJ
GH = 2x+2-x
GH = x+2
HJ = x
JK = HK - HJ
JK = 6x-1-x
JK = 5x-1
GK = x+2+x+5x-1
collect like terms
GK = x+x+5x+2-1
GK = 7x+1
Given GK = 24, then;
7x+1 = 24
7x = 24-1
7x= 23
x = 23/7
Since GH = x+2
GH = 23/7 + 2
GH 23+14/7
GH = 37/7
Also JK = 5x-1
JK = 5(23/7)-1
JK = 115/7 - 1
JK = 115-7/7
JK = 108/7

which graph represents the solution to the inequality y<1/2x-4
The graph shown in option (B) represents the solution to the inequality y<1/2x-4
InequalityA relation between two mathematical expressions which are not equal is known as inequality.
Graphing inequalitiesFirst, solve the given inequality so that y is on the left side and everything else is on the right side.Then, plot the graph for the equation.Finally, we will shade above the line for the ">" and below the line for the "<".Which graph represents y < 1/2x-4?The inequality symbol is "<" (less than).
So, the line of the graph should be dashed and shaded below the line.
Comparing the graphs given in the question, we can conclude that option (B) is correct.
Hence, the graph in option (B) represents the solution to inequality y<1/2x-4.

Answer:
Literally, parallel lines are lines that extend in both directions without meeting.
The three definitions of parallel lines are correct, but Rachel's and Briana's definitions have flaws
Step-by-step explanation:
Rachel
The definition implies that two lines are said to be parallel if they are both perpendicular to another line.
This definition is correct, but the definition brings a new concept; it introduces the concept of line transversal.
Because the parallel lines can be defined without introducing the concept of line transversal (which was not part of the required definition), then we can conclude that the definition has a drawback.
Alex
Alex's definition is correct, and it has no drawback because the definition can be applied to concepts where parallel lines are used.
Briana
Here, Brianna introduced the concept of slopes.
Ideally, parallel lines have the same slope; but the concept is limited to slopes only; and cannot be applied to other concepts such as transversal of lines.

-3x + 1 + 10x = x + 4
Answer: x=1/2
(for anyone who needs the answer)
Answer:
[tex]x=1/2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-3x+1=10x=x+4[/tex]
First, combine like terms on the left:
[tex]7x+1=x+4[/tex]
Subtract 1 from both sides. The left cancels:
[tex](7x+1)-1=(x+4)-1\\7x=x+3[/tex]
Subtract x from both sides. The right cancels:
[tex](7x)-x=(x+3)-x\\6x=3[/tex]
Divide both sides by 6:
[tex](6x)/6=(3)/6\\x=1/2[/tex]
So, our answer is 1/2
Answer:
x = 1/2
Step-by-step explanation:
-3x + 1 + 10x = x + 4 ⇒ simplify left side7x + 1 = x + 4 ⇒ subtract x + 1 from both sides7x - x = 4 - 1 ⇒ simplify6x = 3 ⇒ divide both sides by 6x = 3/6 ⇒ simplifyx = 1/2 ⇒ answerDistribute 6x (5 – 7x).
