Answer:
DI = 38
Step-by-step explanation:
Δ EHC and Δ DIC are similar and ratios of corresponding sides are equal, that is
 =
 =  , substitute values
 , substitute values
 =
 =  ( cross- multiply )
  ( cross- multiply )
2DI = 76 ( divide both sides by 2 )
DI = 38
 
        
             
        
        
        
Let's try the actual solution of the system
<span>y = –2x + 1 
y = –2x – 3
Note that the slopes of the graphs of these two lines are the same:  -2.
That means that the lines are parallel to one another.
Only the y-intercepts (1 and -3) are different.
Since the 2 lines never intersect, the system has no solution.

(-1,-9) because if we substituted 1 into x y would be 9 and if we substituted 1/2 into x y would be 3 but if we substituted -1 into x y would be 1/9 so therefore that value is incorrect
        
             
        
        
        
If a number is 5679, expanded form is 5000+600+70+9
