PLEASE HELP ASAP i don’t have much time.
arlik [135]

Answer:

x=-3, d=2, e=3

Step-by-step explanation:

\frac{9a^3b^5}{-3ab^2} =\frac{9}{-3} \cdot\frac{a^3}{a} \cdot \frac{b^5}{b^2}

Recall how to divide exponents. For instance, a^3/a^1=a^{3-1}=a^2.

=-3a^2b^3

Thus, x=-3, d=2, e=3

25 POINTS PLEASE EXPLAIN AND HELP!!!!!!!!!
Dominik [7]
Remark
You have been just a little bit ambiguous in your notation, those answering cannot be sure what you mean. A small hint. Certain mods will delete these sorts of questions.
I can't get the latex to work properly. 

Condition 1
If you mean y = 8/(x^2 + 4) then 
f(x) = 8/x
g(x) = (x^2 + 4)

Condition two
If you mean y = (8/x^2) + 4 Then
f(x) = 8x + 4
g(x) = 1/ x^2
