John is paying for his families meal. The meal cost $45. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied. What does john pay for the meal? Explain or show your reasoning

  4/9

Step-by-step explanation:

To multiply fractions, first multiply across the numerators, then multiply across the denominators.

So here, we have 2 · 2 which is 4 and 3 · 3 which is 9.

So we have 4/9 which is in lowest terms.

This means that 2/3 · 2/3 is 4/9.

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.
