Answer:
-6 <u>></u> x
Step-by-step explanation:
3 (x-6) +2 ≥ 5x - 4
3x-18 + 2 <u>></u> 5x - 4
3x - 18 <u>></u> 5x - 6
-18 <u>></u> 2x - 6
-12 <u>></u> 2x
-6 <u>> </u>x
 
        
                    
             
        
        
        
Answer:
I would say -6 is an irrational number. 
Step-by-step explanation:
 Either way, -6 is a rational number, because it can be expressed as a fraction where the numerator and denominator are integers and the denominator doesn't equal 0.

Answer:
Therefore x=9
Step-by-step explanation:
Give that,
log x+ log (x-3) = log 54
log x(x-3) =log 54             [     ]
   ]
x(x-3) = 54
Now expand the above equation to get a quadratic equation
x²-3x=54
⇒x²-9x+6x-54=0
⇒x(x-9)+6(x-9)=0
⇒(x-9)(x+6)=0
⇒x-9=0  or, x+6=0
⇒x=9,-6
Now putting x= -6 in the given expression,
log(-6)+log(-6-9)=log 54.
Since log (-6) does not exist.
Therefore x=9
