Question

Which graph represents the solution to the inequality 3x – 5 > -11 ?
​

Answer 1

a

Explanation:

Solving the inequality

3x - 5 ≥ - 11 ( add 5 to both sides )

3x ≥ - 6 ( divide both sides by 3 )

x ≥ - 2

Since x is greater than or equal to - 2, then this is indicated on the number line by a closed circle at - 2

Since x greater than - 2 then the arrow points to the right

This is represented in graph a

Answer 2

b

Explanation:

3x≥-6

x≤-2
