Answer
8.5
Step-by-step explanation:
43 - 3d = d + 9
43 = d + 3d + 9
43 - 9 = 3d + d
34 = 4d
34/4 = 4d/4
8.5 = d
btw its a bit rude just to delete my answer you shouldve just asked for me to show an explanation
Hello,
The graph of y = x² + 1 most certainly is a function.
It is a function because for every value of x, there is only one value of y.
The domain of y = x² + 1 is the set of all real numbers and the range is y ≥ 1.

Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
