Hope this helps!
Didn't know if you wanted the explanation or not, so sorry. But I can put an explanation if you need it.
The difference quotient and simplification will be = [4 -h-2x]
The given equation is as follows: f(x)= 4x - x²
For finding the quotient and further simplification we must follow the following steps:
[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h
<h3>What is simplification of algebraic operations?</h3>
Getting the functions in their lowest terms is known as simplification.
Brackets will get open and solved further;
[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h
[f(x + h) - f(x)] / h = [4h - h² - 2x]/ h
Finally dividing the whole equation with h;
= [4 - h - 2x]

Step-by-step explanation:
is a root of the quadratic
This quadratic isn't factorable so use the quadratic formula
The plus and minus sign after b means we going to have two roots.
The roots are
and
We subsitue those values for Beta.

ANSWER:
________
11 hours
EXPLANTION:
___________
First, find the unit rate for how much Amanda earn per hour
270/18 = 15
Next, divide how much money she needs to earn by how much she earn per house to find out how much hours she need to work to earn that much
165/15 = 11
That is your answer :)
