We have that
 the point J (10,-6)
the rule is-----------(x,y)-------------------> (x-3, y-2)
therefore
J (10,-6)----------------- > (10-3,-6-2)--------> (7,-8)
the answer is 
<span>the y-coordinate of J” is -8</span>
        
                    
             
        
        
        
        
Answer:
The right answer is "5.9". A further solving is provided below.
Step-by-step explanation:
The given values are:
Initial Magnitude,
M₁ = 3.9
Let Second magnitude be M₂.
Now,
⇒  
On substituting the values, we get
⇒  
On putting the value of "log 120", we get
⇒  
On adding "3.9" both sides, we get
⇒  
⇒
