Rule: f(x) = 2x + 2
Ordered Pair (x, y)
Input(x) Output(y)
-1

1
2

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

answer is  

c.

36

step-by-step explanation:

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
