What is the solution to |x − 4| ≥ 7?

9514 1404 393

  (x ≤ -3) ∪ (11 ≤ x)

Step-by-step explanation:

The given equation resolves to two equations:

  x -4 ≥ 7   ⇒   x ≥ 11

  x -4 ≤ -7   ⇒   x ≤ -3

The solution is (x ≤ -3) ∪ (11 ≤ x).

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
