Answer:
A skeleton that has lost 50% of its carbon-14 is 5750 years old.
Step-by-step explanation:
The halflife on an element is the amount it takes to decrease to half it's original amount, that is, when the amount is 50% of the initial amount.
How old is a skeleton that has lost 50% of its carbon-14?
If the skeleton lost 50% of its carbon-14 it has the other 50%, that is, it is in it's half-life.
The radioactive element carbon-14 has a half-life of 5750 years.
This means that a skeleton that has lost 50% of its carbon-14 is 5750 years old.
Answer: That the average price of a 1-bedroom apartment in New York in the year 2000 was around $800.
Step-by-step explanation:
In this case, x represents the number of years after the year 2000.
Then we can think that x = 0, represents the year 2000 itself.
Now, remember that the y-intercept is the value of y when we have x = 0.
Then the y-intercept gives information about the average price of a 1-bedroom apartment in the year 2000.
The information that we can conclude with this is that the average price of a 1-bedroom apartment in New York in the year 2000 was around $800.
The same input is being mapped into two outputs, so this is not a function.
<h3>
Does the table represent a function?</h3>
A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.
Here we have the table:
x y
4 2
3 3
4 5
5 6
7 7
As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.
Then this table does not represent a function.

Answer:
A system of equations is when two or more equations have the same variable(s) that you work with together.
Step-by-step explanation:
For these types of equations, we typically use substitution, elimination, and graphing.
