Answer:

The first equation does not have any, as x^2 always makes the values postive, which causes it to always be greater than 0.

Step-by-step explanation:

The second inequality is x is less than or equal to 4, and greater than or equal to negative 3.

The third inequality is x is greater then or equal to negative 6, and less than negative 3.

The fourth inequality was a bit strange, it gave results that were difficult to graph. However, it seems m is less than or equal to negative 1.2, and greater than or equal to 8.2.

The fifth inequality is x is greater than or equal to negative 2, and less than or equal to 7/2.

Hope this helps!
