Order the steps and justifications in solving the system of linear equations. Equation 1: -2x+y=7
Equation 2:2x+y=-9

-2x + y = 7

2x + y = -9

First, add the equations together...

2y = -2

Divide by 2 on both sides...

y = -1

Now, plug in -1 for y to find x...

2x + (-1) = -9

Add one on both sides...

2x = -8

Divide by 2 on both sides...

x = -4

Your answers are...

x = -4

y = -1

Hope this helps :)

based on context clues you gave i'm assuming the answer would be c.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
