Answer:

4a) 9n - 3

4b) n = 11

Step-by-step explanation:

3(3n - 1)

9n - 3

9n - 3 = 96

9n - 3 + 3 = 96 + 3

9n = 99

9n ÷ 9 = 99 ÷ 9

n = 11

Identify the horizontal asymptote of f(x)=x^2+6x-9 over x-2

lora16 [44]

$\bf \cfrac{x^2+6x-9}{x-2}\qquad 
\begin{cases}
x^2\impliedby \textit{has a degree of 2}\\
x^1\impliedby \textit{has a degree of 1}
\end{cases}$

if the degree of the expression of the numerator is greater than that of the denominator, the rational expression has no horizontal asymptote.
