Answer:
The answer is D.117
Step-by-step explanation:
Supplementary angles equal 180°.
180-63=117
 
        
                    
             
        
        
        
the opposite or addictive increase of 5x is -5x.
the opposite or addictive increase of 5x + 8 is -5x -8.
 
        
                    
             
        
        
        
First question:
I urge you to perform the division using the synthetic division method:
      ________________
-4  /   1   3   -6   -6   8
             -4    4     8  -8
       -----------------------
         1   -1   -2    2    0
Note that there is no remainder.  When this is the case, the divisor (here, that's -4) is a root of the given polynomial, and the value of that polynomial, g(-4), is 0.
If the remainder were not 0, then the remainder represents the value of the polynomial for that particular divisor.  For example, if x = -3, the remainder is -28.  We'd write that as g(-3) = -28.
But here, g(-4) = 0.
        
             
        
        
        
Answer:
x=21/23
Step-by-step explanation:
Solve for x:
3x+5y=21−20x+5y
Add 20x to both sides:
3x+5y+20x=−20x+5y+21+20x
23x+5y=5y+21
Subtract 5y to both sides:
23x+5y+−5y=5y+21+−5y
23x=21
Divide both sides by 23:
x=21/23
