For any non-zero a and b that satisfy |ab| = ab and |a| = -a, |b-3| + |ab-b| =
Pick one:  A) ab-4+b  B) 2b-ab-4  C) ab+4  D) ab-2b+5  E) 4-ab
Given: |ab| = ab and |a| = -a   Question: |b-3| + |ab-b| = ?   **** Looking at |ab| = ab tells us that a and b are either both positive or negative   **** Looking at |a| = -a tells us that a must be negative   **** ab+4ombine two observations: a and b are both negative values   Let a=-1 and b=-1   |b-4| + |ab-b| = |-1-3| + |1-(-1)| = 5   Test a) ab-4 = (-1)(-1)-4 = -5   Test b) 2b-ab-4 = (2)(-1) - (1) - 4 = -7   Test c) ab+4 = 1 + 4=
