Answer:
No solution
Step-by-step explanation:
21−7x=−7x−21−4
21−7x=−7x−25
21=−25
No solution
The graph is a function because when you use the vertical line test it does not hit more than one point at any given place on the line.
Hope this helped :)
The answer would be
x = 160/147
or
x = 1 and 13/147
Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).

To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.
Answer:
The formula is:

Step-by-step explanation:
The geometric sequences are those in which the division between the terms
and
of the sequence are equal to a constant common reason called "r"
The geometrics secencias have the following form:

Where
is the first term of the sequence
In this sequence we have the following terms
1.2, 3, 7.5, 18.75
Then notice that:

Then:
and 
Finally the formula is:
