Answer:

A number line with a closed circle on 9 and shading to the left

Step-by-step explanation:

we have

[tex]2(x+1)\geq 20[/tex]

Solve for x

[tex]2x+2\geq 20[/tex]

[tex]2x\geq 20-2[/tex]

[tex]2x\geq 18[/tex]

[tex]x\geq 18/2[/tex]

[tex]x\geq 9[/tex]

The solution is the interval ----> [9,∞)

All real numbers greater than or equal to 9
