Write an equation passing through a line A(2,0) that is parallel to the line y=3x-5

Mathematics
1 answer:
Helga [31]4 years ago
3 0

Answer:

y = 3x - 6

Step-by-step explanation:

Same slope as y = 3x - 5

Slope is 3

Plug in coordinate and slope, then solve for b (y = mx + b):

0 = (3)(2) + b

b + 6 = 0

b = -6

Rewrite equation:

y = 3x - 6

Calcule la ecuación general de la recta que pasa por la intersección de la recta:

La ecuación general de la recta es x + 3 · y = - 15.

<h3>¿Cómo determinar la ecuación de una recta?</h3>

Según la geometría, una recta es generada por la existencia de dos puntos distintos y en este problema debemos hallar una ecuación de la recta que pasa por la intersección de las dos rectas y otro punto. Primero, determinamos la solución del sistema de ecuaciones lineales para conocer la localización del primer punto:

7 · x - 15 · y = 39                 (1)

5 · x + y = - 19                     (2)

The solución del sistema de ecuaciones lineales is (x, y) = (- 3, - 4).

Segundo, determinamos la pendiente de la recta mediante la fórmula de la recta secante:

m = [- 6 - (- 4)] / [3 - (- 3)]

m = - 1 / 3

Tercero, determinamos el intercepto a partir de la ecuación de la recta:

b = y - m · x

b = - 6 - (- 1 / 3) · 3

b = - 6 + 1

b = - 5

Finalmente, determinamos la ecuación de la recta en su forma general:

y = (- 1 / 3) · x - 5

(1 / 3) · x + y = - 5

x + 3 · y = - 15

La ecuación general de la recta es x + 3 · y = - 15.

Which ordered pair is a solution of the inequality y &gt; 13x + 3
solong [7]

Answer:

x<y-3/13

Step-by-step explanation:

Switch sides'

13x+3<y

Subtract 3 from both sides

13x+3-3<y-3

Simplify

13x<y-3

Divide both sides by 13

13x/13<y/13-3/13

Simplify

x<y-3/13

(13,3)

Tina bought 3 1/2 pounds of turkey and 2 1/4 pounds of cheese she. Used 1 1/2 pounds of cheese to make macaroni and cheese how m
muminat

Answer:6/8 pounds

Step-by-step explanation:

2 1/4 - 1 1/2

- 2 times 4 plus 1 = 9/4

- 1 times 2 plus 1 = 3/2

9/4 - 3/2

-to subtract your fraction, you need to have the same denominator in each side

- 4 times 2 = 8 (this is your denominator)

- 4 times 3 = 12 (your right numerator)

- 2 times 9 = 18 (your left numerator)

18/8 - 12/8 = 6/8
