The most important component of a physical structure is a solid foundation on which the rest of the structure sits. A strong foundation allows buildings to last
longer and withstand many outside forces.
Just like the foundation of a building, a strong foundation for algebra is critical for
success and allows you to extend your understanding to more complex
mathematical and real-world situations. What are some of the foundational, or key, concepts of algebra that you have learned so far?

What is the inverse of the function f(x)=4x+8

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
