step 1 given
step 2 change f(x) to y
step 3 switch x and y
step 4 add 5 to each side
step 5 divide each side by 7
step 6 change y to g(x)
step 7 switch sides of the equation

in step 6, keith should have switched x and y.
b.
keith did not make any errors.
c.
in step 4, keith should have subtracted 5 from each side.

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.
