The graph has a closed circle, the arrow points left and -7 is part of the solution.

Step-by-step explanation:

Consider the provided inequality:

$15\geq 22+x$

Add -x to both sides of the inequality.

$15-x\geq 22+x-x$

$15-x\geq 22$

Now add -15 to both the sides of the inequality.

$-15+15-x\geq 22-15$

$-x\geq 7$

Therefore,

$x\leq -7$

This means x can be any real number which is less then or equal to -7. Thus, the arrow points to the left.

Use an closed circle for the sign $\leq or\geq$

Therefore the correct answer is:

The graph has a closed circle, the arrow points left and -7 is part of the solution.
