Question

Which inequalities would have an open circle when graphed? Check all that apply.

Answer 1

It is given that the inequalities.

We need to determine the inequalities which have an open circle.

The graph will have an open circle only if it has the symbol < or > because it indicates that the boundary is not included.

Option A: $t \geq 25$

The inequality shows that it contains the boundary point 25.

Hence, the inequality $t \geq 25$ does not have an open circle.

Hence, Option A is not the correct answer.

Option B: $-2.5 \leq m$

The inequality shows that it contains the boundary point -2.5.

Hence, the inequality $-2.5 \leq m$ does not have an open circle.

Hence, Option B is not the correct answer.

Option C: $x>5.4$

The inequality shows that it does not contains the boundary point 5.4

Hence, the inequality $x>5.4$ have an open circle.

Thus, Option C is the correct answer.

Option D: $\frac{1}{2}>x$

The inequality shows that it does not contain the boundary point $\frac{1}{2}$

Hence, the inequality $\frac{1}{2}>x$ have an open circle.

Thus, Option D is the correct answer.

Option E: $x>0$

The inequality shows that it does not contain the boundary point 0

Hence, the inequality $x>0$ have an open circle.

Thus, Option E is the correct answer.

Answer 2

Answer:

x > 5.4

One-half less-than x

x > 0

these are correct C D E
