<span>The inequality |2x − 6| less than or equal to 10 can be expressed as two form like this to get two value of x
2x-6 </span>≤<span> 10
2x</span>≤10+6
x≤8<span>
-(</span>2x-6) ≤ 10<span>
2x-6 </span>≥<span> -10
2x</span>≥-10+6
x≥-4
<span>
The graph of the inequality would be: </span>
x≤8 and x≥-4
or
-4≤x≤8
Are u able to take a picture of the whole question?
Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

The odd multiples of 9,
, in the range
form the set

Each member of the set is a term of the arithmetic progression

where the values of
range from 0 to 4, or 
Putting these facts together, we get the result
