Which of the following is not a way to represent the solution of the inequality 5(x + 2) greater than or equal to 7x + 2(x - 1)?

 A number line with a closed circle on 3 and shading to the right
 A number line with a closed circle on 3 and shading to the left
 3 greater than or equal to x
 x less than or greater to 3

radar · Answer

First solve the inequality.
5(x + 2)>=7x + 2(x-1)
5x + 10 >=7x + 2x -2
-4x >=-12 divide by -4
x<=3
Now can you pick out the ones that do NOT described the iequality.
