Answer: No solution
Step-by-step explanation: -12x-14=-62-12x
You would have to simplify the -12x but you can't so this would be a no solution. 
  
        
                    
             
        
        
        
A)your equation for t-mobile would be 
y=20x+100
Topar equation
y=30x 
B) you’d set the two equation equal to each other 
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to 
        
             
        
        
        
Answer:
The answer is D
Step-by-step explanation:
 
        
                    
             
        
        
        
The inequality shown by this graph is  y ≥ 2.
<h3>Describe inequality.</h3>
the relationship between two non-equal expressions using a symbol like "not equal to," ≠ "greater than >," or "less than <  "
The inequality sign : ≥ or ≤ to use is: or because the line is solid and not dotted.
Given that the points have y-coordinate values of 2, (-5, 2), and (3, 2), respectively, and that the line crosses the y-axis at this point, the proper inequality is:
y ≥ 2
Therefore, y ≥  2 is the inequality.

Answer:
The  width is  
Step-by-step explanation:
From the question we are told that 
    The population standard deviation is  
     The  sample size is  
     The sample mean  is  
Given that the confidence level is  99% then the level of significance is mathematically represented as  
                
=>            
=>             
Next we obtain the critical value of   from the normal distribution table, the value is
 from the normal distribution table, the value is 
              
Generally margin of error is mathematically represented as 
              
substituting values 
               
               
                
The width of the 99% confidence interval is mathematically evaluated as 
          
substituting values
