Answer:
An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
Step-by-step explanation:
Answer:

Step-by-step explanation:
If we are to write an equation of the form
, then the function is linear; therefore, it has a constant slope
.
The slope
of the function is given by


thus we have

Now we find
from the fact that the first month of service costs $72.99, which gives us
, or


Substituting the values of
and
, we get our equation in the final form:

Answer:
The solution of given equation is x = -4
Step-by-step explanation:
We are given the following in the question:
Let x be the variable such that

Relation:
The quotient of a number and 4 is negative 1
We can write the equation as:

Solution:

Thus, the solution of given equation is x = -4
