subtract 18c from both sides
13c + 100 - 18c = 18c - 18c
-5c + 100 = 0
##### Group constants
Group our constants 100 and 0.
subtract 100 from both sides... | HuggingFaceTB/finemath | |

# prove this sequence is increasing
The sequence $$A_n$$ is described as- \begin{align*} A_1 & = \sqrt{2}\\ A_{n+1} & =(2+A_n)^{0.5} \end{align*} where $$A_n$$ is the $$n$$th term in the sequence.
I can prove by induction that this sequence is bounded by above by $$2$$ and then find the limit to be $$2$$. But in orde... | HuggingFaceTB/finemath | |

How do you solve |10x + -8| <28?
Apr 28, 2017
See the entire solution process below:
Explanation:
First, rewrite the inequality as:
