Answer 1

From the given inequality graph

6. The solution shown by the graph is

$\begin{gathered} x<0,or,x\ge4 \\ x<0\cong0>x \\ So, \\ 0>x\ge4 \end{gathered}$

7. The solution shown by the graph is

$x<-6,or,x>-3$

$\begin{gathered} x<-6\cong-6>x \\ So, \\ -6>x>-3 \end{gathered}$

8.

The graph of k ≤ -1 is

The graph of k > 4 is

The graph of k ≤ -1, or, k > 4 is
