Answer:
Valid
Step-by-step explanation:
3(x-4)=x+4              <em>Given</em>
3x-12=x+4                <em>Distribute</em>
2x=16<em>                      Subtract x from both sides and add 12 to both sides</em>
x=8                           <em>Divide each side by 2.</em>

An equation for water level in june for pensacola as a function of time (t) is f(t) = 5 cos pi/6 t + 7.
Which equation of cos show period amplitude ?
The equation given below show aplitude and period

 where A = amplitude,
 b = 2 pi/Period, 
Period = 12 hrs,
 c = midline,
 x = t and y = f(t)
We have to find the amplitude 
<h3>What is the formula for the amplitude?</h3>





Therefore, the an equation for water level in june for pensacola as a function of time (t)
