Question

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?

x greater than or equal to −5
x less than or equal to −5
−5 less than or greater to x
A number line with a closed circle on negative 5 and shading to the right

Answer 1

First you need to simplify the left side of the equation to get
`2x-2 \geq -12`
Then you add by two on both sides to get
`2x \geq -10`
Finally you divide by 2 on both sides to get
`x \geq -5`
