“Unit rate” is a comparison of any two separate but related measurements when the second of these measurements is reduced to a value of one. Calculating the unit rate in any set of circumstances will require the use of division.
I just did this a few seconds ago and the correct answer is 78. The check above the number is green which means its correct.
True, you can even test it out yourself. If the domain (x) is the same then it will be a vertical line. Like if you graphed (1,2) (1,4), (1,6) it will be a vertical line on your graph. I hope this helps!
Given:
are in geometric sequences.
To find:
The value of x.
Solution:
If a, b, c are in geometric sequences, then

...(i)
It is given that
are in geometric sequences. By using (i), we get




On further simplification, we get



Therefore, the value of x is 0.
