For any non-zero a and b that satisfy |ab| = ab and |a| = -a, |b-5| + |ab+b| = Choose the correct choice from the following options.
A) ab-4	B) 2b-ab-4	C) ab+4	D) ab-2b+4	E) 4+2ab
Given: |ab| = ab and |a| = -a   Question: |b-5| + |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   **** Combine two observations: a and b are both negative values   Let a=-1 and b=-1   |b-5| + |ab+b| = |-1-5| + |1+(-1)| = 6   Test a) ab-4 = (-1)(-1)-4 = -3   Test b) 2b-ab-4 = (2)(-1) - (1) - 4 = -7   Test c) ab+4 = 1 + 4=
