Question

Solve the inequality. Graph the solution.

$-8\le z+6.4$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow -8\le z+6.4$

$\Rightarrow -8–6.4\le z+6.4–6.4$ [ Subtract $-6.4$ from both sides ]

$\therefore -14.4\le z$

Step 2 : Draw the graph

We have, $-14.4\le z$

So, the graph is

Hence, the required inequality is $-14.4\le \mathrm{z}$ and the required graph is shown above.
