The solution set for the inequation 2x + 4 ≤ 14, x ∈ W is:
(a) {1, 2, 3, 4, 5}
(b) {0, 1, 2, 3, 4, 5}
(c) {1, 2, 3, 4}
(d) {0, 1, 2, 3, 4}
The solution set for the inequation 2x + 4 ≤ 14, x ∈ W is:
(a) {1, 2, 3, 4, 5}
(b) {0, 1, 2, 3, 4, 5}
(c) {1, 2, 3, 4}
(d) {0, 1, 2, 3, 4}
(b) {0, 1, 2, 3, 4, 5}
Explanation:
Given, 2x + 4 ≤ 14
2x ≤ 14 − 4
2x ≤ 10
x\leq\frac{10}{2}x ≤ 5
Since x ∈ W, x can be 0, 1, 2, 3, 4 or 5.
Therefore, the solution set is {0, 1, 2, 3, 4, 5}.
