Answer:
The answer to your question is:  x = -1
Step-by-step explanation:
Data
slope of l = x
slope of m = x +2
they are ⊥
Process
If they are ⊥, then,     x + 2  = - 1/x
                                   x(x + 2) = -1
                                   x² + 2x = -1
                                   x² + 2x + 1  = 0
                                  (x + 1)² = 0
                                  x + 1 = 0
                                 x = -1
 
        
             
        
        
        
Answer:
12y+9.48x=0
Step-by-step explanation:
Note dozen means 12 in mathematics
So 12 muffins cost $9.48 
 X muffins cost $y
So let's cross multiply
12×y=9.48×x
12y=9.48x
Substrate 9.48x from both sides
12y-9.48x=0
So the final equation is 12y-9.48x=0
