Question

Solve the following inequality.

Negative 3.55 less-than-or-equal-to negative 28.4

Which graph shows the correct solution?
A number line going from 3 to 13. An open circle is at 8. Everything to the right of the circle is shaded.
A number line going from 3 to 13. An open circle is at 8. Everything to the left of the circle is shaded.
A number line going from 3 to 13. A closed circle is at 8. Everything to the right of the circle is shaded.

Answer 1

Check the numbers: -3.55 > -28.4, so the statement -3.55 ≤ -28.4 is false. There is no number that makes it true, so the solution set is empty. None of the four graphs (all of which show nonempty solution sets) is correct.
