R is the midpoint of Qs. If Qr=4x and Rs=x+9 what is QrI’ll mark you brainlidt

The value of QR is 12.

Step-by-step explanation:

We are given that R is the midpoint of QS, and by definition of a midpoint we know that R is equidistant from the endpoints of segment QS. Therefore, we know that the length of QR is equal to the length of RS. Now we can form an algebraic equation with the values of the segments: 4x = x+9. Now we can subtract x from both sides of this equation to get 3x = 9. Now we can divide both sides by 3, to get that x = 3. Now we can plug this number into the expression 4x, to get the value of QR to be 12.

sorry not sure

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! : )
