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:

Answer:
So basically you add x with 9 and you get 9x
Answer:
ab= 11 and bc = 8
Step-by-step explanation:
B is correct, because there is only 1 output for each input.
<em>9 - 4(2p - 1) =45</em>
<em>5(2p - 1) = 45</em>
<em>10p - 5 = 45</em>
<em>10p = 45 + 5</em>
<em>10p = 50</em>
<em>p = 50/10</em>
<em>p =5 (ans)</em>
