A) -8 < z < 4  B) z > 2  C) z > -8  D) z < 4  E) None of the above
Two points:   1) z &lt; 8   2) 2z &gt; -4 or z &gt; -2   From 1 and 2: -2 &lt; z &lt; 8   (A) is not true because z could be &gt; 4.   (B) is not true because z could be &lt; 2.   (C) is true because z's value is always &gt; -8.   (D) is not true because z could be &gt;4.   (E) is not true because z &gt; -8 is true.
