12/14=6/7
Because you divide by 2.
Answer:
I beleive it is the first one, but I am not 100% sure. Sorry
Step-by-step explanation:
Answer: 
Step-by-step explanation:
By definition the domain of an inverse function 
is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function 
, then to find the inverse function, follow these steps:
1. Make 
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with
. Then the inverse function is:
Answer: A. 20%
Step-by-step explanation:
First, to find the total number of teachers, we can add 25+32+18+5+20=100
Next, we divide the number of teachers in 2014 (20) by the total number of teachers (100) as follows:
20 ÷ 100 = 0.2
Finally, to make 0.2 a percentage, we can multiply 0.2 X 100 = 20
Therefore, the correct answer is A.
Answer: the first option is the correct answer.
Step-by-step explanation:
Let x represent the number of necklaces that he makes in a year.
Profit = Revenue - cost
The cost of making each necklace is $5. In making necklaces in a year, the fixed cost is $5000. This means that the total cost of making x necklaces in a year is
5x + 5000
Sam sells each necklace for $10 each. This means that the total amount made from selling x necklaces is $10x.
For Sam to make profit of $1000 in a year, the number of necklaces that she must sell would be
1000 = 10x - (5x + 5000)
1000 = 10x - 5x - 5000
10x - 5x = 1000 + 5000
5x = 6000
x = 6000/5
x = 1200
