Camila tiene un pastel. Ella se come 45 de este y le da el resto a su hermano Samuel, él se come 45 de lo que recibe. Posteriormente, le regala el resto a su amigo Daniel, el cual se come la mitad de lo recibido y el resto se la da a Valentina. ¿Qué porcentaje de pastel de Camila recibió Valentina?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
