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
You can factor a parabola by finding its roots: if
has roots , then you have the following factorization:
In order to find the roots, you can use the usual formula
In the first example, this formula leads to
So, you can factor
The same goes for the second parabola.
As for the third exercise, simply plug the values asking
you get
Add 3 to both sides:
Divide both sides by 1.5:
Answer:No because if you add 5 plus 4 you will get nine but when u subtract 5 from four you will get 1 so no it would not get you any of those

Answer:
Step-by-step explanation:
Given a vector < x, y > then its magnitude is
Given the directed line segment
P (0, 0 ) → Q (3, 2 ) then
PQ = q - p = (3, 2 ) - (0, 0 ) = < 3 - 0, 2 - 0 > = < 3 , 2 >
| PQ | = = =
4/12ths is 1/3 when simplified. 1/3 in decimal form is .33
1/5; 1/5 is .2
¼; ¼ is .25
5/25: 5/25 is .2
6/24; 6/24 is .25
all of these fractions are near .33 but aren't equivalent to it.
