Question

Es la forma ordinaria de la ecuación x+y+20x-8y+115=0​

Answer 1

Respuesta:

x+y+20x-8y+115 = 0

(1+20)x+(1-8)y+115 = 0

21x+(-7y)+115 = 0

21x-7y+115 = 0

21x-7y+21x+115 = 0+21x

-7y+115 = 21x

-(-7y+115) = -(21x)

7y-115 = 21x

7y-115+115 = 21x+115

7y = 21x+115

7y/7 = (21x+115)/7

y = (21/7)x+(115/7)

y = 3x+(115/7)

R// " y = 3x+(115/7) " es la fórmula ordinaria de la ecuación de la recta " x+y+20x-8y+115 = 0 " .
