The domain is the charity amount and range is the donation.
<h3>How to find the domain and range?</h3>
The collection of all x values, or independent quantity, for which the function f(x) exists or is defined, is known as the domain. Range is the collection of all y values, the dependent quantity, that are produced when all x values (the domain) are substituted into the function. All x and y values that could be used to solve the inequality are referred to as the domain and range, respectively. A solution is any set of values that could be used to prove the inequality.
Given: The amount to be donated is 250 dollars and half of the charity amount.
Let x= donation amount and y= charity amount
This can be written as x= f(y) where x= 250+y/2
Thus since domain is an independent variable therefore charity is the domain and range being the dependent variable, donation would be considered as range.

The model (x+a)(x-a) will represents the factors of 4x²-9 as (2x+3)(2x-3).
<h3>What are the quadratic equations in one variable completing the squares method?</h3>
The "completing the squares" method aims to construct a quadratic equation of the form where the x variable is entirely covered by a single squared term, which is the square of a linear expression in x, as the name suggests.
The quadratic equation can resemble this:
x²-a² = (x+a)(x-a)
Given equation;
⇒4x²-9
⇒(2x)²-3²
The equation can be modeled as;
(2x+3)(2x-3)
Hence the model (x+a)(x-b) will represents the factors of 4x²-9 as (2x+3)(2x-3).

Yes, I believe this is linear
93×10^6 = 93000000
It is equal to 93 million (with exactly 6 zeroes).
Answer:
23
Step-by-step explanation:
2x+14+x+7=90, 3x+21=90,3x=90-21. 3x=69, x=23
