Agroup of 5 friends is out to dinner. each of the friends will order the dinner special, and they have a coupon for $10 off the entire bill. which equation can be used to find the total cost of all the dinners after the coupon is applied?

answer:

5d-10=c

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

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.
