Question

Which of the following is not a way to represent the solution of the inequality 2(x - 1) greater than or equal to 10?

x greater than or equal to 6
6 less than or equal to x
A number line with a closed circle on 6 and shading to the left
A number line with a closed circle on 6 and shading to the right

Answer 1

Answer 2

2(x - 1) >= 10 --- divide both sides by 2
x - 1 >= 5 --- add 1 to both sides
x >= 6 or 6 <= x

since there is an equal sign, the circle will be closed and since x is greater then 6, it is shaded to the right.

so that just leaves one incorrect....and that would be the 3rd answer choice
