Hey! So if anyone has a spare minute, I just need to figure out how to express an overall answer to an equality problem in interval notation. I was asked to solve 6t≤7t-8 or 2−2t>20 seperately. I got t≥8 ( [8,∞ ) in interval notation) and t <-9 ( or (-∞ ,-9) ). Now that I have those answers, how do I use those answers to solve the overall problem and express that in interval notation? Sorry if this seems like a pretty easy question I've fallen behind because of sickness and have found it difficult to find anything else about this specifically on the internet. Thanks for the help in advance If I were to guess at the problem I would think that the answer was something like (-9,8] but I'm 99% sure that would be wrong.
