A system of two linear equations is shown below 2x + 3y = 6
- + 4y = 8
Henrietta claims that replacing the equation 2: + 3y = 6 with a different equation sometimes produces a
system with the same solutions. Select three equations that can be used to support Henrietta's claim.
А
3 + 7y= 14
B
23 -8y = -16
с
4x - 5y = -10
D
-2 + 15y = 30

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.
