The answer is DDDD, because if you plug in all the values of x and y into the equation like this..
y=x-3
A - 5=-2-3 >> 5=-5 >> not correct
B 2= -5-3 >> 2=-8 >> not correct
C 5=2-3 >> 5=-1 >> not correct
D 2=5-3 >> 2=2 >> CORRECT
D is the only correct answer!
If you divide 4 by 14 you get 0.29 and if you convert it to a fraction you get 29/100
the geometric mean is 20
the geometric mean of 2 numbers a and b is 
= 
= 20
The answer is 1,100
i hope this help
