To solve the inequality \(-1 > \frac{d}{2} + 1\), we can follow these steps:
-
Isolate the term with \(d\): \[ -1 > \frac{d}{2} + 1 \] Subtract \(1\) from both sides: \[ -1 - 1 > \frac{d}{2} \] \[ -2 > \frac{d}{2} \]
-
Eliminate the fraction by multiplying both sides by \(2\): \[ -2 \cdot 2 > d \] \[ -4 > d \] This can be rewritten as: \[ d < -4 \]
The solution to the inequality is: \[ d < -4 \]
Graphing the solution:
To graph this solution on a number line:
- Draw a number line.
- Place an open circle at \(-4\) to indicate that \(-4\) is not included in the solution.
- Shade the line to the left of \(-4\) to show that all values less than \(-4\) are part of the solution.
