To solve the inequality \( \frac{p}{2} + 5 > 4 \), follow these steps:
-
Subtract 5 from both sides: \[ \frac{p}{2} > 4 - 5 \] \[ \frac{p}{2} > -1 \]
-
Multiply both sides by 2 (note that multiplying or dividing by a positive number does not change the inequality): \[ p > -2 \]
The solution to the inequality is \( p > -2 \).
Graphing the solution:
To graph \( p > -2 \):
- Draw a number line.
- Mark the point at -2.
- Since it's a strict inequality (greater than, not greater than or equal to), draw an open circle at -2 to indicate that -2 is not included in the solution.
- Shade to the right of -2 to show all numbers greater than -2.
Here’s a simple representation of the graph:

-2
In this graph:
- The open circle (o) at -2 indicates that -2 is not part of the solution.
- The shaded line to the right indicates all values greater than -2 are included in the solution.
