Al resolver un sistema de ecuaciones usando el método de elinación, ¿cuál corresponde al paso 1? Resolver la ecuación resultante

Multiplicar si es necesario, para poder cancelar la misma variable

Sustituir y resolver para determinar el valor de la segunda variable

Sumar ambas ecuaciones: Ec 1 y Ec 2

the answer is 489

step-by-step explanation:

a 270° rotation about point p says on e d g e n u it y (had to space it out because it says it's a misspelling so i couldn't submit it

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. : )
