There are values of m and z fulfilling both conditions, some of which result in m+z>0, and others which result in m+z<0. E.g. m=-2, z=-1 --> m+z<0 m=2, z=-1 --> m+z<0 Similarly, using the graph method suggested, there are values m+z can be positive or negative. So, I think the statements are insuffi...
