See explanation
Step-by-step explanation:
Now we have to know what type of sequence that 6, 18, 54, 162,... is
Recall that for a geometric sequence, the common ratio (r) is constant
r = 18/6 = 3
r = 54/18 = 3
r = 162/54 = 3
The recursive formula for the geometric sequence is; 
The iterative formula is 
Answer:
2
Step-by-step explanation:
3(x-4)=-6
3x - 12 =-6
3x=- 6 +12
3x =6
x =6 :3
x=2
Answer:
b is -mx+y and m is -b+y/x
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x = 
(x + 9) + 3 = 3 ( subtract 3 from both sides )
(x + 9) = 0 , then
x + 9 = 
= 1 ( subtract 9 from both sides )
x = - 8
Answer:
Supplementary and Linear Pair
Step-by-step explanation:
The angles 1 and 2 form 180 degrees. That is the definition of a Supplementary Angle and Linear Pair.
