Answer: 13x^(2)+3x+18
Step-by-step explanation:
13x^(2)+3x+18
Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system

If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
From the information above he makes 15 cups in 5 days .
The domain for n is 
Explanation:
The arithmetic sequence is
To determine the domain of the sequence, let us consider
as
Thus, the sequence becomes,
The domain of the function is the set of all x-values for which the function is real and well defined.
Since, the function has no domain constraints or undefined points. Therefore, the domain of the function is
Thus, the domain of the arithmetic sequence
is
