The table below shows unit sales for Snowboard Ventures new rubber handy man carry machine. The machines are sold at local ski hills. Which two ski hills had the lowest percentage increase year over year in unit sales from 2009 to 2010?

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

21

step-by-step explanation:

y > 1/3x

y < = -x + 4

hope this : )

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.
