Question

For the following inequality, indicate whether the boundary line should be dashed or solid. x ≤ 5 dashed solid.

Answer 1

Answer:solid I think

Explanation:

Answer 2

Solid

Explanation:

Rewriting for the sake of clarity:

1) For the following inequality, indicate whether the boundary line should be dashed or solid. x ≤ 5

2) Since it is a closed interval which includes the number 5 then this can also be written as:

`(-\infty,5]`

3) Hence, we can graph it as a solid line crossing the point (5,0). For the x coordinate 5, is within the interval.
