Answer 2

but my answer choices were:
a: |x-21|≥7
b: |x-7|≥21
c: |x-21|≤7
d: |x-7|≤21

Answer 3

|x−a|≤b

This represents the set of all points (x) that are less than or equal to b points from a.

a is the middle point between the min and max. To find it, you need to find out how far they are apart:
|min−max|

Divide that by 2 and you get b.

min + b = midpoint = a
max - b = midpoint = a

Answer 4

this is good information i dont know how they are getting 7 and 21 when the numbers are 14 and 28

Answer 5

Use my equations and put in min = 14, max = 28

Solve for a and b and then put them into the first equation.
