Which describes a correct way to construct a scatterplot?
When analyzing the number of junk e-mails received each day of the week, the number of junk e-mails is the independent
variable.
When analyzing the number of cups of hot tea that are sold during days with varying average temperatures, temperature is
the dependent variable.
When analyzing shoe size according to height, shoe size is the independent variable.
When analyzing the number of boys who participate in volleyball each year for several years, the number of boys is the
dependent variable.

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

a and c

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! : )
