PLEASE HELP!! IF YOU ANSWER I WILL GIVE YOU BRAINLIST At 5:00 a. m., the temperature outside was 6°F below zero. By 12:00 p. m., it rose by 9°F. At 7:00 p. m., the temperature dropped by 5°F. What was the evening temperature?

A.

–20°F

B.

20°F

C.

8°F

D.

-2°F

D.

(The only option that makes sense is D. but I came up with 10°F when I did the math)

8 2/3 is the answer

step-by-step explanation: just use a calculator

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! : )
