Question

Can someone double check my work?
Thanks~


A quality control inspector is in charge of inspecting drill bits that are produced on an assembly line. The diameter of a drill bit can be modeled by the equation |x − 0.525| = 0.01. Show your work in solving the equation to determine the minimum and maximum diameters of the drill bits.
|x – 0.525| = 0.01

Answer 1

I've come up with
.4 => x <= .6

Answer 2

Ok give me a minute

Answer 3

Okay :]

Answer 4

|x - .5| = .1
is the same as |x - .5| <= .1 the maximum that some thing can be is .1 then certainly it can be less than that.
-.1 <= x - .5 <= .1
which is -.1 + .5 <= x <= .1 + .5
same as .4 <= x <= .6

So in words: As the minimum that the diameter can be is .4 and the maximum that it can be is .6.

Answer 5

Oh so I have them reversed :)
it should be...
.4 <= x >= .6

Answer 6

There u go ^~^

Answer 7

awesome! Thank you very much!
