What is the slope of a line perpendicular to the line whose equation is x-3y=-18

Answers

Answer 1

Answer: y = 3x + 2

Step-by-step explanation: Convert the equation to slope intercept form to get y = –1/3x + 2.  The old slope is –1/3 and the new slope is 3.  Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

Determinar que Recipiente tiene mayor densidad; el recipiente A pesa 1.2 toneladas y tiene un volumen de 120 m³ mientras que el recipiente B pesa 2.4 toneladas y tiene un volumen de 240 m³. ¿Cuál recipiente tiene mayor densidad?

Answers

Answer:

Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.

Step-by-step explanation:

Recordamos que la densidad de un material uniforme ([tex]\rho[/tex]), medido en kilogramos por metro cúbico, está definido por:

[tex]\rho = \frac{m}{V}[/tex] (1)

Donde:

[tex]m[/tex] - Masa, medido en kilogramos.

[tex]V[/tex] - Volumen, medido en metros cúbicos.

Ahora calculamos la densidad de cada recipiente:

Recipiente A ([tex]m =1200\,kg[/tex], [tex]V = 120\,m^{3}[/tex])

[tex]\rho = \frac{1200\,kg}{120\,m^{3}}[/tex]

[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]

El recipiente A tiene una densidad de 10 kilogramos por metro cúbico.

Recipiente B ([tex]m = 2400\,kg[/tex], [tex]V = 240\,m^{3}[/tex])

[tex]\rho = \frac{2400\,kg}{240\,m^{3}}[/tex]

[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]

El recipiente B tiene una densidad de 10 kilogramos por metro cúbico.

Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.

Answer:

  (a) after 5 minutes: tower 1 -- 1550 gallons; tower 2 -- 670 gallons

  (b) 1650-20m = 570+20m; m = 27 . . . minutes

Step-by-step explanation:

(a) At the rate of 20 gallons per minute, in 5 minutes the amount of water transferred will be ...

  (20 gal/min)(5 min) = 100 gal

That is, Tower 1 will have 100 gallons less: 1650 -100 = 1550 gallons

and Tower 2 will have 100 gallons more: 570 +100 = 670 gallons.

__

(b) The quantity in tower 1 is ...

  t1 = 1650 -20m

and the quantity in tower 2 is ...

  t2 = 570 +20m

These will be equal when ...

  t1 = t2

  1650 -20m = 570 +20m . . . . . equation for finding m

  1080 = 40m . . . . . . . add 20m-570

What is the inverse of the function f(x) = 2x + 1?

Answers

Answer:

y = x/2 -1/2

Step-by-step explanation:

let’s write this equation as

y = 2x + 1

to find the inverse let’s switch x and y

x = 2y + 1

and solve for y

x -1 = 2y

y = x/2 -1/2

so the inverse is

okay so for the #1 it says that it take 1/2 (half) a day to paint 1/4 of your bedroom and we want to know how many days it would take to paint all of the bedroom, so 4/4 of the bedroom.
We can say that
1/2(number of day) = 1/4(how much you painted)
to paint all of your room you would have to have painted 4/4 of your room
to get to 4/4 i multiplied 1/4 by 4
you do the same thing to 1/2 so 1/2•4=2
So it would take 2 days to paint all (4/4) of your bed room

I dont if im clear but just think about it
If you take half a day to pain 1/4 of your room, in one day you would’ve painted 2/4 of your room, so in one day you paint 2/4 of your room. And in 2 days you paint 4/4 of your room

Instructions: Write and solve an equation to find the measure or angle x.

Answers

Answer:

x = 30

Step-by-step explanation:

Okay the triangle should add up to 180.

The square represents a right angle = 90°

So just do this

60° + 90° + x = 180 (collect like terms)

150° + x  = 180 (subtract 150 on both sides)

x = 30

Hope this helps ya!

Answer:

x = 30

Step-by-step explanation:

the trinagle has an angle of 180.

and the trainage has a 90°  next to the 60

So

60° + 90° + x = 180 (there are term)

150° + x  = 180

subtract 150 on both sides

150 - 150  180-150 =  x = 30

Write the equation of the line through (2,3) and (-1,-12) in slope
intercept form.

will give brainliest

Answers

Answer:

  y = 5x - 7

Step-by-step explanation:

slope m = (y₂ - y₁) / (x₂ - x₁)

              = (-12 - 3) / (-1 - 2)

              = (-12 - 3) / (-1 - 2)

              = -15 / -3

          m = 5

y-intercept using slope above and anyone point, let's use (-1, -12):

y = mx + b

-12 = 5(-1) + b

-12 = -5 + b

b = -7

Equation of line using m and b from above:

y = mx + b

y = 5x - 7

What is an equation ?

An equation is comparing two equal quantities in different form.Equations can be of many types like algebraic equation, logarithmic equation,trigonometric equations, exponential equations.We can also graph this equations in 2 dimensional and 3 dimensional plane.

According to the question given an equation 3x - 6 = 21 first we have to solve for x or find the value of x.

∴ 3x - 6 = 21.

3x = 21 + 6.

3x = 27.

x = 27/3.

x = 9.

So, the value of (x-2) will be (9-2) = 7.

Step-by-step explanation:

The area of a square piece of paper is 200 square inches.

We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper​. It is shown in the attached figure.

Area of a square = x², x is the side length

[tex]x=\sqrt{A} \\\\x=\sqrt{200} \\\\x=14.142\ \text{inches}[/tex]

Sally and Joan were able to dust the house in 3 hours together. It takes Joan 10 hours to finish the same job alone. Without help, how long would it take Sally to finish the same job ?

Answers

Answer:

4.3 hours

Step-by-step explanation:

Let the number of hours Sally does a job = x

Let the number did hours Joan does a job be equal to y

Sally and Joan were able to dust the house in 3 hours together.

1/x + 1/y = 1/3

It takes Joan 10 hours to finish the same job alone.

Hence,

1/x + 1/10 = 1/3

1/x = 1/3 - 1/10

Least common dey = 30

1/x = 10 - 3/30

1/x = 7/30

Cross Multiply

x × 7 = 30

7x = 30

x = 30/7

x = 4.2857142857 hours

Approximately = 4.3 hours

Without help, it would take Sally 4.3 hours to finish the same job.

La factura de celular del mes pasado ascendió a un total de $239 por un consumo de 269 minutos de llamada, mientras que la de este mes ascendió a $175 por un consumo de 141 minutos. El importe es la suma de una tasa fija (renta de línea) más un precio fijo por minuto. Calcular la tasa y el precio por minuto

Answers

Answer:

Costo fijo= $104.5

Costo unitario=  $0.5 por minuto

Step-by-step explanation:

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

Primero debemos calcular el cost por minuto de llamada:

Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario=  $0.5 por minuto

Ahora, el costo fijo:

Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5

just need 5 and 6 done due in 20 minutes plz help​

Answers

Step-by-step explanation:

5. Let the equation of the line be y = mx + c

m = (6-15)/(2-(-1)) = -3

sub (2, 6) and m = -3:

6 = -3(2) + c

c = 12

Equation of the line: y = -3x + 12

6. Let the equation of the line be y = mx + c

y-intercept of 7 means c = 7

y = mx + 7

x-intercept: value of x when y = 0

therefore, sub (4, 0):

0 = m(4) + 7

m = -7/4

Equation of the line: y = -7/4x + 7
