Answer:
he forgot to put the decimal point
Step-by-step explanation:
answer is 1.05. 
 
        
                    
             
        
        
        
Under a counterclockwise rotation about the origin of 90°
a point (x , y ) → (- y, x ), hence
A(2, 1 ) → A'(- 1, 2 )
 
        
                    
             
        
        
        
The given equation is  
 
We need to solve the equation for q.
<u>Value of q:</u>
The value of q can be determined by solving the equation  for q.
 for q.
Thus, subtracting both sides of the equation by r, we get;

Now, dividing both sides of the equation by b, we have;

Simplifying the terms, we get;

Therefore, the value of q is 
Hence, Option B is the correct answer.
