Answer:
Step-by-step explanation:
m (x) = (x+ 5) / (x -1) and n(x) = x - 3.
Hence
but n is a function and n = x-3. Now, replace value of n on m (n)
simplify it
since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is
among options, only C has the same denominator with
Hence their domains are the same.
Answer:
<u>131 seats</u> are in the 30th row.
Step-by-step explanation:
The theater is designed with the first row there are 15 seats, in second row 19 seats and in the third row there are 23 seats.
Now, to find the number of seats in the 30th row.
So, we get the common difference() from the arithmetic sequence first:
Thus,
So, the first tem = 15.
The number of last row () = 30.
Now, to get the number of seat in the 30th row we put formula:
Therefore, 131 seats are in the 30th row.
