| 50 QuestionsNote from the author:

A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Solve It! Complete the table below. Enter only a number without commas and use fraction form if necessary. For example: 15000 or -3/10.

Problem 4 Got It? A population of insects triples every week. The number of insects is modeled by the expression below, where w is the number of weeks after the population is measured.

Evaluate the expression for w = -2, w = 0, and w = 1. Match the weeks below with their related populations. Not all populations will be used.

- w = -2
- w = 0
- w = 1

- 400 insects
- 600 insects
- 5400 insects
- 6800 insects
- 16,200 insects
