The sum of Annie's, Bert's, and Chris's ages is 75. Annie is older than Bert by the same number of years that Bert is older than Chris. When Bert is as old as Annie is now, Annie will be three times as old as Chris is now. Let a represent Annie's age, b represent Bert's age, and c represent Chris's age. Set up an appropriate system of linear equations that can be used to determine each of their ages. Condition Equation The sum of Annie's, Bert's, and Chris's ages is 75. Correct: Your answer is correct. Annie is older than Bert by the same number of years that Bert is older than Chris. Correct: Your answer is correct. When Bert is as old as Annie is now, Annie will be three times as old as Chris is now. $$ Incorrect: Your answer is incorrect. Solve the system of equations. What are their ages

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.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
