Answer: D
Step-by-step explanation:
-7 isn't greater than -4
Answer:
0.5
Step-by-step explanation:
The given ordered pairs are: (1,2) (2,2.5) (3,3) (4,3.5) (5,4)
The corresponding sequence is :
2,2.5,3,3.5, 4,....
We can see that there is a common difference of d=0.5.
Better still we could use the slope formula:

We substitute the point (1,2) and (2,2.5).
The rate of change of this sequence is:

The answer is -10.
I hope this is right...
1: if u use the same measures they will be congruent angles.
2: because the segment is being cut in half.
3: their has to be an intersection in the arcs<span />
