Solve the inequality for x, assuming that a, b, and c are positive constants.
(a) a(bx − c) ≥ bc

(Choose the correct answer)
1.[0, c/a]
2. (c/b, bc/a)
3. [c/a + c/b, infinity)
4. (bc, a(b-c)/bc]
5. (-infinity, c/b]

Answer :

Nirina7
a(bx − c) ≥ bc, implies (bx − c) ≥ bc /a  and then  bx  ≥ bc/a + c, x≥ c/a +c/b
so the solution is 3. [c/a + c/b, infinity)
