There are four parts to a quarter so you divide 28 by 4:
28/4=7
and then because you want to know three quarters you just times 7 by 3:
7x3=21
therefore three quarters of 28 is 21
Given:
The function is
To find:
The correct ordered pairs.
Solution:
We have,
For x=3,
So, the ordered pair is 
.
For x=-2,
![[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28%5Cdfrac%7Ba%7D%7Bb%7D%29%5E%7B-n%7D%3D%28%5Cdfrac%7Bb%7D%7Ba%7D%29%5En%5D)
So, the ordered pair is 
.
For x=1,
So, the ordered pair is 
.
For x=-1,
So, the ordered pair is (-1,5). This is the correct answer.
Therefore, the correct option is D.
For the first question,
Square-root 5 is NOT a rational number.
It’s irrational because, in decimal form, the number goes on forever and has no repeating numbers in decimal form.
Question 2
Pi is NOT rational.
Pi goes on forever and doesn’t repeat.
