Two students use different methods to solve this multiplication problem:

25⋅−1558

wyatt writes each number as a fraction and then multiplies.

2 5 2
• −15 = • =
5 8 5

abigail writes the mixed number as a sum and uses the distributive property.

2 5 2 5 2 2
• −15 = ( −15 + − ) = •
+ • =
+
5 8 5 8 5 5

wyatt's and abigail’s answers will be equal. write the answer as a mixed number in simplest form.

1. 34

2. 268

3. x=14.4

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.
