Por Berta

Para reformar su cocina, Berta compró la semana pasada 2 cajas de baldosas de plaquetas para el suelo y 4 cajas de baldosas para la pared por 200 €.

2x + 4y = 200 ...... Ecuación 1

Hoy

Hoy compré 2 cajas más de plaquetas y otras 2 de tejas por 130 €.

2x + 2y = 130 ..... Ecuación 2

Resolvemos usando el método de Eliminación

2x + 4y = 200 ...... Ecuación 1

2x + 2y = 130 ..... Ecuación 2

Restar la ecuación 2 de 1

2 años = 70

y = 70/2

y = 35 €

Resolviendo para x

2x + 4y = 200 ...... Ecuación 1.

2x + 4 × 35 = 200

2x + 140 = 200

2x = 200 - 140

2x = 60

x = 60/2

x = 30 €

el costo de

Caja de plaquetas = x = 30 €

Caja de azulejos = y = 35 €

Which equations represent the line that’s passes through points (1,-5) and (3,-17)
Nutka1998 [239]

(1,-5)(3,-17)

slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6


y = mx + b

slope(m) = -6

use either of ur points...(1,-5)...x = 1 and y = -5

now we sub and find b, the y int

-5 = -6(1) + b

-5 = -6 + b

-5 + 6 = b

1 = b

so ur equation is : y = -6x + 1....or 6x + y = 1

Hope this helps!
