Step-by-step explanation:
3x-47=65
3x=65+47
3x=112
x=37.3
Hello there, to answer your question...
<h2>1.95 is 1.5% of 130.</h2><h2 />
I hope the information I provided has helped.
If we just have

that's an amplitude of 1 and a period of 
Let's modify this step by step.
Amplitude of 4. Four times the amplitude means a factor of 4 on the outside.

Period of π. Double the period means a factor of 2 on the inside.

Horizontal shift of π/2 to the left. To the left means adding a positive number to x. The question appear ambiguous. It's not clear to me if we add to x or 2x; let's make it

Vertical shift of 3:


Depending on the interpretation of the phase shift, that pi may be a pi/2.
