The first picture about the rational numbers I am not sure the answer.
In the second picture the set that are all equivalent to the fraction is the second set.
In the third picture
the equivalent expression is the first one.
In the fourth picture the correct situation is the first one about buying popcorn.
Hope this helps a little, sorry I could not help more.
Answer:
0
Step-by-step explanation:
1/3 m -1 -1/2 n
Let m =21 and n =12
1/3 (21) - 1 - 1/2 (12)
Multiply
7 - 1 - 6
Subtract
6-6
0
Applying the rules, it is found that ordered pair (24,6), option A, works for both rules.
---------------------
The rule 1 is that y is x divided by 4, that is:
The rule 2 is that y is x subtracted from 18, that is:
In item A, we have that the input x = 24, thus, the results of the expressions are:
In both cases, ordered pair (24,6), thus <u>option A is the answer.</u>

Answer:
Step-by-step explanation:
C, (1,7)
The domain is the set of all point where you can evaluate the function.
As you can see, the first piece is defined from -infinity to 2 (included).
The second piece is defined from 2 to 6 (excluded).
The third piece is defined from 6 (excluded) to +infinity.
So, the domain of the function is composed by all the real numbers which are not 6:
As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.
The second piece is constantly equal to 2, so it adds nothing.
The third piece spans the y axis from -2 to -infinity, so the range is
