Solve the equation by using the combination method

3x-2y=12

-3x+8y=-6

Combine the 2 equations:

3x-2y=12

-3x+8y=-6

6y = 6, which tells us that y=1.

Now subst. 1 for y in the 2nd equation: -3x +8(1) = -6.

Then 14=3x, and x = 14/3.

The solution is (14/3,1).

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.
