Answer:
Step-by-step explanation:
1. 1 Simplify 2+6-4d to -4d+8.
7 ( -4d + 8)
therefor, the answer is, 7( -4d + 8)
You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.
In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.
