Answer:
(4,-8)
Step-by-step explanation:
Plug in the answers for the equations.
 
        
             
        
        
        
Try this option:
according to the condition w+l=48 and w*l=95.
Using these two equation:
 
 
        
        
        
If 2 eggs with bacon cost 2.70, and 1 egg with bacon costs 1.80, that means that 1 egg costs 0.90, so when we subtract once more 0.90 we get the price of the bacon alone, which is in this case 0.90.
 
        
             
        
        
        
Unlike the previous problem, this one requires application of the Law of Cosines.  You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines:  a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
                           40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math.  Solve for cos Q, and then find Q in degrees and Q in radians.
        
                    
             
        
        
        
It would be the first one (x,-y) because say for example you take the point of v1 (4,-1) and reflect across x axis you get (4,1) for v
