Question

Solve the inequality. 8x-5>_27. A.x>_4. B.x>_11/4. C.x<_4. D.x<_11/4

Answer 1

8x - 5 ≥ 27
8x ≥ 32 <-- Add 5 to both sides
x ≥ 4 <-- Divide both sides by 8

So, to be in solution set, x has to be greater or equal to 4.

In interval notation: [4, ∞)

In a set builder notation: {x | x ∈ R, x ≥ 4}
