Keisha is walking around a track that is 400 yards long. she has walked around the track 5 times so far. how many more yards does she need to walk around to complete 2 miles?

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

one set of data has more variation than the other. hope this !

b). 4320 have a nice day

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
