Using the absolute value concept, it is found that the solution is:
---------------------------------
The absolute value of a point, or of a function, measures it's distance to the origin.The inequality given by:![|y - 9| \leq 12](/tpl/images/0928/6826/e95e8.png)
The distance to the origin is of at most 12 between -12 and 12, thus:![-12 \leq y - 9 \leq 12](/tpl/images/0928/6826/83077.png)
We have to solve both inequalities, and find the intersection.![y \leq 21](/tpl/images/0928/6826/80c51.png)
The intersection is values of y between -3 and 21(and logical operator, not or), inclusive, thus:A similar problem, involving absolute value, is given at link

10^6= 2,930,000, 5,000,000, 4,030,000
10^-4=0.0006, 0.00012
Step-by-step explanation:
if u do 10^-4 u get 0.0001
which means that any decimal belongs to 10^-4
hope this helps
