Answer:
y = 0 is the midline equation.
Step-by-step explanation:
The midline equation of y = 2 sin( pi/2 x+3) is the same as that of 
                                          y = 2 sin( pi/2 x+3) or y = sin( pi/2 x+3), and is
                                           y = 0.

Lets Sean's age be x
Helen's age by y
x/y=3/5
x=3/5y
Second equation
2(x-2)=y-2
on solving u get Helen as 10 and Sean as 6
        
             
        
        
        
Answer:
Yes
