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.
use division;
82 ÷ 4 = 20.5
so 4 goes into 82 only 20 times evenly.
hope that helps :D
Answer:
Step-by-step explanation:
Note that the base angle of an isosceles triangle is equal hence;
3x+2 = 5x-30
3x - 5x = -30-2
-2x = -32
x = -32/-2
x = 16
Hence one of the base angle = 3(16)+2 = 50degrees
The sum of angle in the triangle is 180, hence
50+50+y = 180
100 + y = 180
y = 80 degrees
Hence the third angle is 80 degrees

Answer:
4%
Step-by-step explanation:
The unemployment rate is calculated by dividing the number of unemployed(2 million) by the labor force (50million) and multiplying the result by 100.
Labor force is the total number of unemployed and employed persons in a country. In this case, we have:
Labor force= No. of unemployed (in million) + No. of full time employed (in million) + No. of part time employed (in million) = 2 + 38 + 10 = 50 million
Unemployment rate= 2/50 × 100 = 4%
Therefore, the rate of unemployment is 4%.
