Answer asap will give brainliest boris solves the system of equations using the linear combination method. 3x+4y=−87x−3y=6 which steps would allow him to eliminate the y terms in the system of equations? multiply 3x+4y=−8 by 3. multiply 7x−3y=6 by 4. add the resulting equations together. multiply 3x+4y=−8 by 7. multiply 7x−3y=6 by −3 . add the resulting equations together. multiply 3x+4y=−8 by 4. multiply 7x−3y=6 by 3. add the resulting equations together. multiply 3x+4y=−8 by −3 . multiply 7x−3y=6 by 7. add the resulting equations together.

step-by-step explanation:

because there are always 10 numbers in a phone number.

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! : )
