Which system of equations below has exactly one solution? y = –8x – 6 and y = –8x + 6 y = –8x – 6 and 1/2 = –4x – 3 y = –8x – 6 and y = 8x – 6 y = –8x – 6 and –y = 8x + 6

answer:

2 or 3

step-by-step explanation:

in y = -8x - 6 and y = -4x - 3, since the slopes aren't the same, we know that this is the answer. but, the thir one also has slopes that are different, meaning that the answer is two and three.

step-by-step explanation:

where is the questions

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! : )
