Four students compared their running speeds. Each student represented their data in a different format.
Select the names of all of the students who ran at a faster rate than Amy, based on the information given, where x is the time, in minutes, and
y is the distance traveled, in miles.
Amy ran 2 miles in 36 minutes.

40% off the regular price is the correct answer.

step-by-step explanation:

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

as before, graphs and tables allow us to estimate at best.

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.

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
