Answer:
An open circle at 32 and everything to the right of the circle is shaded.
Step-by-step explanation:
[tex]-\dfrac12p < -16[/tex]
Divide both sides by -1 (remembering to reverse the sign):
[tex]\implies \dfrac12p > 16[/tex]
[tex]\implies p > 32[/tex]
Open circle: < or >
Closed circle: ≤ or ≥
Therefore, open circle at 32 and everything to the right of the circle is shaded.
