Answer: 6.3
Step-by-step explanation:
The formula for geometric mean is given as :
G.m = 
Therefore , the geometric mean between 4 and 10 will be :
G.m = 
= 
= 2
= 6.3
Every x value should have only one value of y.
So the answer is the last choice.
The answer for x is x= 4 11/21
All of them??? or just one
