Answer:
CD and DE are perpendicular because their slopes are -1/3 and 3
Step-by-step explanation:
Perpendicular lines will always have the opposite reciprocal.
 
        
             
        
        
        
Since there are no specific requirements given other than expression written using exponents, I am just going to give some examples.
1. 5x^2 - 3
2. 8^5 - 15x + 7
3. 15x^10 - 8x^7 + 16x^5 + 17^3 - 4^2 +13x - 2
        
             
        
        
        
Answer:
57.420
Step-by-step explanation:
The y intercept is always the number on the out side next to the slope which is 2.391
 
        
                    
             
        
        
        
if x is 8 then 12(8) + 12
12 times 8 is 96
96 + 12=108
the answer is 108
 
        
                    
             
        
        
        
3•2-3•4
6-12=-30
-6=-30
