Write an equation that is parallel to the line x + 3y = 2 and passes through the point (1, 0).
Nady [450]

Answer:

y = -1/3x + 1/3

Step-by-step explanation:

x+3y=2

3y = 2 - x

y = 2/3 - 1/3x

y = -1/3x +2/3

the slope is -1/3 and the equation that is parallel will have the same slope also

y = mx + b

y = -1/3x + b

0 = -1/3(1) + b

0 = -1/3 + b

1/3 = b

y = -1/3x + 1/3

Look at Attachment, giving a lot of points for the answer to questions.
tatiyna

Answer:

see below

Step-by-step explanation:

1.

m = (y2-y1)/(x2-x1)

    = (90-80)/(0-1)

     = 10/-1

   =-10

The slope is -10 ft/s

This means the height decreases 10 ft for every second that passes

This is not proportional because it has to go through the point (0,0)

4.

m = (y2-y1)/(x2-x1)

    = (1000-0)/(3-0)

     = 1000/3

   =1000/3

The slope is $1000/3

This means the 1000 dollars is sold every 3 days

This is proportional because it goes through the point (0,0) and has a constant slope

Se tiene que elaborar un cartel de forma triangular, uno de los lados debe medir 30 cm y el otro
Marianna [84]

La medida aproximada del lado faltante según el teorema de desigualdad de triángulos es:

  • más de 12 cm y menos de 48 cm

De acuerdo con el teorema de la desigualdad del triángulo que establece que;

La suma de la longitud de 2 lados cualesquiera de un triángulo debe ser mayor que el tercer lado.

Dado que :

a = 30 cm; b = 18 cm; c =?

Basado en el teorema de la desigualdad del triángulo;

  • c debe ser <(a + b)
  • c <(30 + 18); c <48 cm
  • También c> (a - b)
  • c> (30 - 18); c> 12 cm

Por lo tanto, el lado faltante debe ser menor que 48 y mayor que 12.

Find the equation of a straight line passing through the point (0,1) which is perpendicular to the line y=-2x+2
alexandr1967 [171]

Answer:

y = \frac{1}{2} x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-2} = \frac{1}{2}

The line crosses the y- axis at (0, 1) ⇒ c = 1 , then

y = \frac{1}{2} x + 1 ← equation of perpendicular line
