  1. End-of-Course Testing Algebra I

  2. Multiple Choice Use order of operations to simplify or rewrite variable expressions. Which of these expressions is equivalent to (3x)2? 6x 6x2 9x 9x2

  3. Multiple Choice Model real-life situations using linear expressions, equations, and inequalities. A school has 12 computers. The school receives 6 more computers each time a grant is approved. Which expressionshows the number of computers the school will have aftern technology grants are approved? 12n + 6 6n + 12 12n - 6 6n - 12

  4. Multiple Choice Use significant digits in computational problems. A chemist measures the mass of an object as 21.4 grams. She measures the mass of the second object as 13.94 grams.Which of these shows the combined mass of the two objects,with the correct number of significant digits. 35 grams 35.3 grams 35.36 grams 35.4 grams

  5. Multiple Choice Dylan applied for a summer job doing data entry. His typing test score was 56, and his spelling test score was 87. According to the flow chart, which of these will occur? Dylan will be hired. Dylan will not be hired. Dylan will take a second typing test. Dylan will take a second spelling test. Follow and interpret processes expressed in flow charts.

  6. Constructed Response Compare and contrast linear functions algebraically in terms of their rates of change and intercepts. In 2003, two scientists began studying the number of black bears in a forest. To model the number of black bears, Dr. Becker uses the equation N=9t + 114, and Dr. Yang uses the equation N=9t + 110, where N is the number of black bears, and t is the number of years after 2003. Based on the equations, which scientist expects the number of black bears to increase faster? Explain the reasoning. Dr. Yan because the rate of increase is given by the slope. Dr Yang’s slope is greater than Dr. Becker’s.
