Answer:
Costo total= $1.120.000
Step-by-step explanation:
Dada la siguiente información:
Se necesita instalar el piso de una habitacion de forma rectangular cuyas dimensiones son 7 m por 8 m.
Costo por m2= $20.000
Primero debemos calcular el total de metros cuadrados de la habitación:
Totalm2= 7*8= 56m2
Ahora el costo total:
Costo total= 56*20.000
Costo total= $1.120.000

Quadrant I's points will always be (+,+). It is located in the upper right section.
Quadrant II's points will always be (-,+). It is located in the upper left section.
Quadrant III's points will always be (-,-). It is located in the lower left section.
Quadrant IV's points will always be (+,-). It is located in the lower right section.
The x-coordinate and y-coordinate are both negative, which is the right statement. The best choice is B.
When determining the location of points or other geometrical elements on a manifold, such as Euclidean space, a coordinate system in geometry uses one or more numbers or coordinates.
The value of the coordinate x and the value of the coordinate y are both negative in the fourth quadrant's coordinate system.
As a result, it is true to say that both the x- and y-coordinates are negative. The correct response is B.

The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Step-by-step explanation:
The general equation of the circunferece is defined by the following formula:
[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)
We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]
The system of linear equations is:
[tex]3\cdot A + C = -9[/tex] (2)
[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)
[tex]A -2\cdot B + C = -5[/tex] (4)
The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].

Answer:
x=3
y=1
Step-by-step explanation:
-2x - 7y = -13
3x + 6y = 15
3(-2x - 7y = -13) = -6x - 21y = -39
2(3x + 6y = 15) = 6x + 12y = 30
-6x - 21y = -39
---------------------- The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9
6x + 12y = 30
Therefore, you can say that -9y = -9 so y = 1
FInally, plug that back into either one of the original equations:
3x + 6(1) =15
3x = 9
x = 3

Y+3= -5(x-1) write the equation in slope intercept form
Answer: The equation in slope-intercept form: [tex]y=-5x+2[/tex]
Step-by-step explanation:
The given equation of a line : [tex]y+3= -5(x-1)[/tex]
The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.
We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get
[tex]y+3=-5x+5[/tex]
Subtract 3 from both sides, we get
[tex]y=-5x-2[/tex]
Hence, the equation in slope-intercept form: [tex]y=-5x+2[/tex]

128= 4^2x times 2^x
What is x?
Answer:
x=7/5
Step-by-step explanation:
We can write it in exponential form
128= 2^2*2x * 2^x
2^4x+x=5x
2^5x=128
2^5x=2^7
5x=7
x=7/5
The value of x in the equation given is
[tex] \frac{7}{5} [/tex]
To solve :
[tex]128 = {4}^{2x} \times {2}^{x} [/tex]
Change all values to have the same root :
[tex] {2}^{7} = {2}^{2(2x)} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{4x} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{(4x + x)} [/tex]
[tex] {2}^{7} = {2}^{5x} [/tex]
The roots cancel out
[tex] 7 = 5x[/tex]
Divide both sides by 5
[tex]x = \frac{7}{5} [/tex]
Therefore, the value of
[tex]x = \frac{7}{5} [/tex]

This is the exterior angle theorem, so
x+30+x+22=130
2x+52=130
2x=78
x=39
sooooooooooooo
39+22=61 degrees
61 degrees
Answer:
21
Step-by-step explanation:
First set up the equation
130 + x + 30 + x + 22 = 180 (triangle angles always add up to 180)
then start to solve to find x
130 +2x + 30 + 22 = 180
182 + 2x = 180
-182 -182
2x = -2
/2 /2
x = -1
Then just plug it back into the equation
-1 + 22
