5) Diseñar un sistema de ecuaciones lineales y resolverlo a través del método de Gaussiana, que permita resolver el siguiente problema: -Un ingeniero realiza las siguientes observaciones sobre las ventas de impresoras en una tienda: Hay impresoras Epson, Hp y Cannon. El número de impresoras Epson y Hp es cinco veces el número de las Cannon. Además, el número de impresoras Epson es el triple que el de la Cannon y el total de impresoras Cannon y Hp asciende a 12.
Answer:
[tex]X=12[/tex]
[tex]Y=8[/tex]
[tex]Z=4[/tex]
Step-by-step explanation:
Comencemos definiendo las variables ⇒
[tex]X:[/tex] '' Número de impresoras Epson ''
[tex]Y:[/tex] '' Número de impresoras Hp ''
[tex]Z:[/tex] '' Número de impresoras Cannon ''
Ahora , dado que tenemos las variables definidas podemos escribir el sistema de ecuaciones lineales
''El número de impresoras Epson y Hp es cinco veces el número de las Cannon''
Para esa oración escribimos la siguiente ecuación :
[tex]X+Y=5Z[/tex] (I) que se puede reescribir como
[tex]X+Y-5Z=0[/tex] (II)
''El número de impresoras Epson es el triple que el de las Cannon''
Para esa oración escribimos la siguiente ecuación :
[tex]X=3Z[/tex] (III) que se puede reescribir como
[tex]X-3Z=0[/tex] (IV)
''El total de impresoras Cannon y Hp asciende a 12''
Para ésta última frase escribimos la última ecuación :
[tex]Y+Z=12[/tex] (V)
Con (II), (IV) y (V) armamos el sistema de ecuaciones lineales :
[tex]X+Y-5Z=0\\X-3Z=0\\Y+Z=12[/tex]
Lo resolvemos a través del método de Gauss insertando el sistema en una matriz y realizando operaciones de fila entre las respectivas filas de la matriz :
[tex]\left[\begin{array}{ccxc}1&1&-5&0\\1&0&-3&0\\0&1&1&12\end{array}\right][/tex]
Realizando operaciones entre filas se lleva a la siguiente matriz equivalente :
[tex]\left[\begin{array}{cccc}1&1&-5&0\\0&-1&2&0\\0&0&3&12\end{array}\right][/tex] En esta matriz el sistema de ecuaciones asociado es
[tex]X+Y-5Z=0\\-Y+2Z=0\\3Z=12[/tex]
De aquí encontramos que [tex]Z=4[/tex] , [tex]Y=8[/tex] y [tex]X=12[/tex] (encontramos primero el valor de [tex]Z[/tex] en la última ecuación, de allí reemplazamos en la segunda ecuación para hallar el valor de [tex]Y[/tex]. Finalmente el valor de [tex]X[/tex] se calcula con la primera ecuación)
La solución a éste sistema de ecuaciones es
[tex]X=12[/tex]
[tex]Y=8[/tex]
[tex]Z=4[/tex]
Es recomendable reemplazar éstos valores en el sistema original para verificarlos.

Identify the matrix transformation of ΔMNO, which has coordinates M(1, 3),N(5, 2), and O(3, −3), for a translation 2 units left and 4 units up. Then identify the correct vertices of the image
Answer:
M(-1,7), N(3,6), O(1,1)
Step-by-step explanation:
The coordinates of ΔMNO are M(1, 3),N(5, 2), and O(3, −3).For a translation, 2 units left and 4 units up the correct vertices of the image will be M'(-1,7), N'(3,6), and O'(1,1).
It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that the coordinates are M(1, 3),N(5, 2), and O(3, −3).
We have to translate 2 units left and 4 units up.
The coordinates obtained after applying the given geometric transformation are M'(-1,7), N'(3,6), O'(1,1)
Thus, the coordinates of ΔMNO are M(1, 3),N(5, 2), and O(3, −3).For a translation, 2 units left and 4 units up the correct vertices of the image will be M'(-1,7), N'(3,6), and O'(1,1).

I am confused on the steps to get 3!
Answer:
y=3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5y+ −1/2=7
Step 2: Add 1/2 to both sides.
5y+/−1/2+1/2=7+1/2
5y=15/2
Step 3: Divide both sides by 5.
5y/5

y=3/2
The solution of the given equation is y = 3/2.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have given the equation as
⇒ 5y - 1/2 = 7
Add 1/2 to both sides in the above equation.
⇒ 5y - 1/2 + 1/2 = 7 + 1/2
⇒ 5y = 15/2
Divide both sides by 5
⇒ y = 15/10
⇒ y = 3/2
Hence, the solution of the given equation is y = 3/2.

Please help and give an explanation!:)
Answer: D) All real numbers greater than or equal to -4.
Explanation:
The lowest point occurs when y = -4, which is where the vertex is located.
The range consists of y values such that y = -4 or y > -4. We can shorten that last sentence to say [tex]y \ge -4[/tex]. So y is greater than or equal to -4.
As you can probably tell, the range is the set of all possible outputs of a function.

4 friends shot free throws for a charity event. Adam scored 8 more points than Cheryl. Laura scored twice as many points as Adam. Tom scored 10 points less than Laura. Together the four friends scored a total of 66 points.
Answer:
c = 6
a = 14
l = 28
t = 18
Step-by-step explanation:
Free throws are usually worth one point each. We can assign variables and use equations to link information between Adam, Cheryl, Laura, and Tom. Then, we can just substitute in our information and solve.
"Adam scored 8 more points than Cheryl"
a = c + 8
"Laura scored twice as many points as Adam"
l = 2a
"Tom scored 10 points less than Laura"
t = l - 10
"Together the four friends scored a total of 66 points"
a + c + l + t = 66
Now we substitute in our variables and solve from there (see attached image)
c = 6
a = 14
l = 28
t = 18

What is the value of x?
Answer:
x = 50
Step-by-step explanation:
these are vertical angles meaning they are congruent so
[2(x+10)] = (3x-30) then use distributive property
(2x+20) = (3x-30) subtract 2x from both sides
20 = x - 30 add 30 to both sides
x = 50
Answer:
x = 50
Step-by-step explanation:
We know that 2(x+10) = (3x-30) because it is on opposite sides of an "x".
We just set them equal to each other and solve for x!
2(x+10) = 3x - 30
2x + 20 = 3x - 30
20 = x - 30
50 = x

The Jeffer's company has a debt ratio (total debt to total assets) of 0.365. If their total debt is $500,000, what are their total assets?
Given:
Total debt ratio (total debt to total assets) = 0.365
Total debt = $500,000
To find:
The total assets.
Solution:
We know that,
[tex]\text{Total debt ratio}=\dfrac{\text{Total debt}}{\text{Total assets}}[/tex]
On substituting the given values, we get
[tex]0.365=\dfrac{500,000}{\text{Total assets}}[/tex]
[tex]\text{Total assets}=\dfrac{500,000}{0.365}[/tex]
[tex]\text{Total assets}=1369863.0137[/tex]
Therefore, the value of total assets is $1369863.0137.
Solve the equation -2/3d - 1/4d = -22 for d.
Answer:
d=24
Step-by-step explanation:
create a common denominator of 12
[tex]\frac{-2}{3}[/tex]d-[tex]\frac{1}{4}[/tex]d=[tex]\frac{-22}{1}[/tex]
[tex]\frac{-2}{3}[/tex]*4 [tex]\frac{1}{4}[/tex]*3 [tex]\frac{-22}{1}[/tex]*12
[tex]\frac{-8}{12}[/tex]d - [tex]\frac{3}{12}[/tex]d = [tex]\frac{-264}{12}[/tex]
[tex]\frac{-11}{12}[/tex]d=[tex]\frac{-264}{12}[/tex]
multiple each side by reciprocal ([tex]\frac{12}{-11}[/tex]) and simplify
d=24
The value of d from the given equation is 24.
The given equation is [tex]-\frac{2}{3}d - \frac{1}{4}d=-22[/tex].
We need to solve the given equation for d.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved for d as follows:
Take LCM of denominators
LCM of denominators 3 and 4 is 12
Now equate denominators to LCM, that is
[tex]d(-\frac{2}{3} - \frac{1}{4})=-22[/tex]
⇒ [tex]d(-\frac{8}{12} - \frac{3}{12})=-22[/tex]
⇒ [tex]d(\frac{-8-3}{12} )=-22[/tex]
⇒ [tex]d(\frac{-11}{12} )=-22[/tex]
⇒ d=24
Therefore, the value of d from the given equation is 24.

Answer:
After solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.
Option B is correct.
Step-by-step explanation:
We need to solve [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]
Solving:
[tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]
Cross multiply
[tex](x-2)(x+4)=x*4[/tex]
Multiplying:
[tex]x(x+4)-2(x+4)=4x\\x^2+4x-2x-8=4x\\x^2+2x-8-4x=0\\x^2-2x-8=0[/tex]
Now, we have got quadratic equation [tex]x^2-2x-8=0[/tex]
Solving this quadratic equation using quadratic formula
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]
We have a=1, b=-2 and c=-8 Putting values
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-8)}}{2(1)}\\x=\frac{2\pm\sqrt{4+32}}{2}\\x=\frac{2\pm\sqrt{36}}{2}\\x=\frac{2\pm6}{2}\\x=\frac{2+6}{2} \ or \ x=\frac{2-6}{2}\\x=\frac{8}{2} \ or \ x=\frac{-4}{2}\\x=4 \ or \ x=-2[/tex]
So,after solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.
Option B is correct.
