A jewelry maker cuts pieces of wire to shape into earrings. The equation
|x – 12.2% = 0.3 gives the minimum and
maximum acceptable lengths of the wires
in centimeters. What is the minimum
acceptable length of a wire?

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

126 maybe. sorry

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
