Answer 1

5^(х²-5х-6)≥5^0
х²-5х-6≥0
     х²-5х-6=0
    х1+х2=5
   х1*х2=-6        х1=6      х2=-1        (х-6)(х+1)≥0
                                      
                                    ---------\-1 ------------------------6-\-------- х
                 в интервале  от -∞ до  -1  (+)
      в интервале  от -1 до 6(-)  ,    в интервале от  6 до  +∞  (+)           
   нас интересует  знак (+)    Ответ:х∈(-∞;-1]U[6;+∞) 

Answer 2

Question Details

The question asks to solve the equation -2/9=5,6 in detail and provide a thorough explanation.

Step 1) Write the equation in standard form

-2/9 = 5.6

Step 2) Multiply both sides by 9 to remove the fraction

-2 = 50.4

Step 3) Divide both sides by -2 to isolate the variable

1 = -25.2

However, this is impossible since a number cannot be both positive and negative at the same time.

Conclusion

Therefore, there is no solution to this equation. We can conclude that the equation -2/9 = 5.6 is invalid since it leads to a contradiction.
