Question

Which number(s) below belong to the solution set of the inequality? Check all that apply.

Answer 1

4x ≥ 112

It's very simple.Just replace x by the values from A to F so:

A. x = 21 ⇒ 4·21 ≥ 112 ⇒ 84 ≥ 112        - FALSE
B. x = 33 ⇒ 4·33 ≥ 112 ⇒ 132 ≥ 112      - TRUE
C. x = 27 ⇒ 4·27 ≥ 112 ⇒   98 ≥ 112      - FALSE
D. x = 1   ⇒  4·1  ≥ 112 ⇒     4 ≥ 112      - FALSE
E. x = 28 ⇒ 28·4  ≥ 112 ⇒ 112 ≥ 112     - TRUE
F. x = 25 ⇒ 25·4  ≥ 112 ⇒  100 ≥ 112     - FALSE

ANSWER : 33,28
