George paid $179.76 for a new lawn mower, after tax, and the tax rate is 7%. What was the original price of the lawn mower?

168

Step-by-step explanation:

Let's make the original price of the lawn as "x"

x + x * 7/100 = 179.76

=> x + 7x / 100 = 179.76

=> 100x/100 + 7x/100 = 179.76

=> 107x = 17976

=> 107x/107 = 17976/107

=> x = 168

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.
