The first step would be to isolate the square root on the left side.  √x-6+2 = 6 √x-6 = -2+6  √x-6 = 4We would have to take away the radical on the left and square the equation.  (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22
        
             
        
        
        
Answer:

Step-by-step explanation:
 [1]    2x + y = -1
   [2]    x - 2y = -8  <------- given linear equations
Graphic Representation of the Equations : ----> given in attatchment
 y + 2x = -1        -2y + x = -8  < ----- point where they connect is shown in graph
Solve by Substitution :
// Solve equation [2] for the variable  x 
 
  [2]    x = 2y - 8
// Plug this in for variable  x  in equation [1]
   [1]    2•(2y-8) + y = -1
   [1]    5y = 15
// Solve equation [1] for the variable  y 
   [1]    5y = 15 
   [1]    y = 3 
// By now we know this much :
    x = 2y-8
    y = 3
// Use the  y  value to solve for  x 
    x = 2(3)-8 = -2 
Solution :
 {x,y} = {-2,3} 
 
        
                    
             
        
        
        
Answer:
32760 ways
Step-by-step explanation:
Given
Number of Candidates = 15
Job Positions = 4
Required:
Number of outcomes
This question represent selection; i.e. selecting candidates for job positions;
This question can be solved in any of the following two ways
Method 1. 
The first candidate can be chosen from any of the 15 candidates
The second candidate can be chosen from any of the remaining 14 candidates
The third candidate can be chosen from any of the remaining 13 candidates
The fourth candidate can be chosen from any of the remaining 12 candidates
Total Possible Selection = 15 * 14 * 13 * 12
<em>Total Possible Selection = 32760 ways</em>
<em></em>
Method 2:
This can be solved using permutation method which goes thus;

Where n = 15 and r = 4
So;
 becomes
 becomes





<em>Hence, there are 32760 ways</em>
