Find the common ratio of the give sequence, and write an exponential function which represents the sequence. use n=1, 2, 3, .. a)3; f(n)=81^n-1 b)3; f(n)=81(3)^n-1 c)1/3; f(n)=81(3)^n-1 d)1/3; f(n)=81(1/3)^n-1

d

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
