anonymous · Answer

making the inequality

amistre64 · Answer

start with 32 in the middle, then add/subtract 8 from it

amistre64 · Answer

24 <= 32 <= 40

this is the range, but working out the absolute value for it ... hmmm

anonymous · Answer

oh

amistre64 · Answer

lets subtract 32 from everything now

-8 <= 0 <= 8 ; and let x be the center

-8 <= x <= 8

we want an equation that has the solution  x = |8|
