Answer:
63.1 pounds
Step-by-step explanation:
1. Change the percentage into a decimal.
12.5% ↔ .125
2. multiply the percentage as a decimal with 72.
72x.125= 9 (this is the same as what is 12.5% of 72)
3. Subtract the number you just got from 72
72-9= 63
The answer is C. Because, of the fact that the key words of the question is Evaluate the increase in respiratory illnesses among citizens.
Answer:
A
Step-by-step explanation:
Because the have the same slope.
The second equation solving for y is:
Y= -2x+7.
Both equations have the same slope of -2
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).
