Answer:
we determine that none of the ordered pair is a solution of   as none of the ordered pairs satisfy the equation.
  as none of the ordered pairs satisfy the equation.
Step-by-step explanation:
Considering the equation

- Putting (-5,2) in the equation


 ∵ L.H.S ≠ R.H.S
         ∵ L.H.S ≠ R.H.S 
FALSE
- Putting (0,-5) in the equation


 ∵ L.H.S ≠ R.H.S
       ∵ L.H.S ≠ R.H.S 
FALSE
- Putting (5,1) in the equation


 ∵ L.H.S ≠ R.H.S
          ∵ L.H.S ≠ R.H.S 
FALSE
- Putting (7,5) in the equation


 ∵ L.H.S ≠ R.H.S
          ∵ L.H.S ≠ R.H.S 
FALSE
From the above calculations, we determine that none of the ordered pair is a solution of   as none of the ordered pairs satisfy the equation.
  as none of the ordered pairs satisfy the equation.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
x has to be equal to or less than a -5 to get (4 + x) to be a negative number.
x has to be equal to or greater than -10 for (11 + x) to be a positive number.
Therefore, any number between -10 and -5 will work.
