There is only one answer, x=7
64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
The general equation of the sine function y=f(x) is defined as

where A is the Amplitude
B represents the frequency of the function with period equals 
C represents the Horizontal shift, For Phase shift= -C/B
D represents the Vertical shift.
The data given that the amplitude of the function A=6

Vertical shift 
Horizontal Shift 
Now plug in
in the general equation of sine function, we get
