Answer:
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:
[tex]15\geq 22+x[/tex]
Add -x to both sides of the inequality.
[tex]15-x\geq 22+x-x[/tex]
[tex]15-x\geq 22[/tex]
Now add -15 to both the sides of the inequality.
[tex]-15+15-x\geq 22-15[/tex]
[tex]-x\geq 7[/tex]
Therefore,
[tex]x\leq -7[/tex]
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 [tex]\leq or\geq[/tex]
Therefore the correct answer is:
The graph has a closed circle, the arrow points left and -7 is part of the solution.
