Ответ:
First step: you got to add y to both sides in the math problem Ex: 15x - y + y < 12 + y
Second step: simplify 15x < 12 + y
Third Step: This you got to divide both sides by 15 like this: 15x/15 < 12/15 + y/15
Last and Fourth step: Simplify and thats your answer x < 12 + y/15

Part A: Geometric Sequence
Part B:![a_1 = 4, a_n = 2a_{n-1}](/tpl/images/0708/0598/1d568.png)
Part C: a₈ = 512
Step-by-step explanation:
When we find the common ratio between the y-values (x-values are n inputs), we should see that we get r = 2. That means we have a geometric sequence.
Because we have a geometric sequence, our recursive formula is:
. Simply plug in our known variables:
Now we need to find what y is when x = 8, so (I used explicit formula):
a₈ = 512
