To solve the inequality 7d - 20 ≥ -76, we need to isolate the variable d.
1. Add 20 to both sides of the inequality:
7d - 20 + 20 ≥ -76 + 20
7d ≥ -56
2. Divide both sides by 7:
7d/7 ≥ -56/7
d ≥ -8
The solution to the inequality is d ≥ -8.
To graph the solution on a number line, we start by plotting a closed circle at -8 (since the inequality is "greater than or equal to"). Then we extend a ray to the right, indicating that any value greater than or equal to -8 is a solution.

To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.
