Mateo begins his dive at sea level. He dives down 15 meters, and then rises up 4 meters. He dives again, going down 7 meters. Which equation models Mateo’s movements, and uses the commutative property? (–15) + 4 + (–7) = (–7) + (–15) + (–4) (–15) + 4 + (–7) = 7 + 15 + (–4) (–15) + 4 + (–7) = 4 + (–15) + (–7) (–15) + 4 + (–7) = 4 + 15 + 7

chase is right because he already been to the swings and he know how far it will be to get there

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! : )

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
