Question

2(х-1)>5х-4(2х+1)-решите неравенство. И рисунок

Answer 1

2х-2>5х-8х-4

2х-5х+8х>2-4

5х>-2

х<-2/5

х<-0,4

 

Answer 2

2х-2>5x-8x-4

2x+3x>-2

5x>-2

x>-0,4

Answer 3

Let's start by simplifying the inequality:

2(x-1) > 5x - 4(2x+1)

2x - 2 > 5x - 8x - 4

2x - 2 > -3x - 4

2x + 3x > -4 + 2

5x > -2

x > -2/5

So the solution to the inequality is x > -2/5. We can represent this on a number line as follows:

cssCopy code
      <-------------------|------o=======>
                         -2/5

The circle at -2/5 is open because x cannot equal -2/5, since that would make the left side of the inequality equal to the right side. The arrow points to the right, indicating that all values of x greater than -2/5 satisfy the inequality.

I hope that helps! Let me know if you have any more questions.
