Answer 1

The answer is x less than or equal to 6 and x is greater than or equal to -2.4.
I'm sorry I didn't put the signs but you should be able to figure that out. I hope this helps!

Answer 2

The graph in the attached figure

Explanation:

we have

`5x-9\leq 21`

solve the inequality

`5x\leq 21+9`

`5x\leq 30`

`x\leq 30/5`

`x\leq 6`

The solution is the interval----------> (-∞,6]

All real numbers less than or equal to
`6`

The solution of the inequality is the shaded area to the left of the solid line
