The rule I'm going to use is if |x| <= k, then -k <= x <= k where k is some positive number The notation <= means "less than or equal to"
|2x-6| <= 10 -10 <= 2x-6 <= 10 ... use the rule mentioned above -10+6 <= 2x-6+6 <= 10+6 ... add 6 to all sides -4 <= 2x <= 16 -4/2 <= 2x/2 <= 16/2 ... divide all sides by 2 -2 <= x <= 8
So we'll have a number line with closed circles at -2 and 8. The shaded region is between the closed circles. This is a shorthand way of saying what choice A is saying. For some reason, your teacher decided to make the wording more clunky. Saying "shading to the right of -2 and shading to the left of 8" is the same as "shading between -2 and 8" So that's why choice A is the answer
Note: the closed circle indicates we include the endpoint as part of the solution set, or shaded region.
