An industrial laser cuts steel plates that are 11.93 meters long. the laser can have an error value of at most 0.02 meters. the inequality |x − | ≤ can be used to find the range of acceptable lengths for the steel plates. the range of acceptable lengths for the steel plates is ≤ x ≤

Step-by-step explanation:

Error is the difference from the nominal value, hence the nominal value is what is subtracted from x. We want the magnitude of that difference, | x-11.93 |, to be less than the maximum error value, 0.02, so the inequality is ...

  |x -11.93| ≤ 0.02

We can solve this by "unfolding" it, then adding 11.93:

  -0.02 ≤ x -11.93 ≤ 0.02

  11.91 ≤ x ≤ 11.95

i can you with this sweetie!
