Mrs. Carver is trying to find out how many lab coats she had initially started the year with. Twelve of her lab coats were ruined, and she is left with 22. Salman said to use the equation c – 12 = 22, he said, "I'm looking for a number, c, that is 12 less than 22, so c = 10." (Please i beg u somebody help, NO LINKS.) Which statement best describes the flaw in Salman's reasoning?
A
Salman's answer is right, but he should have just subtracted 12 from both sides of the equation.

B
Salman's answer is wrong, but he explained the equation correctly.

C
Salman's equation is set up correctly, but his explanation of what it represents is incorrect.

D
Salman should have subtracted the 22 from the 12 instead of 12 from the 22.

answer: are you

step-by-step explanation:

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! : )
