Which statements are true about the solution of 15> (with line underneath it) 22 + x ? check all that apply.
the graph has a closed circle.
the graph has an open circle.
the arrow points left.
the arrow points right.
–7 is part of the solution.
–6 is part of the solution.

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:

Add -x to both sides of the inequality.

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

Therefore,

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

Therefore the correct answer is:

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