  1. Day 20: TURN TO next page, begin the warm up • -4 and 4 are __________ because they have the same absolute value but different signs. • Compare 6x+3 and -2x+4 when x=-3 • Evaluate w-(wy-y) w=-4 and y=-1 Warm up

  2. Homework 16. C 17. Student B; Student A added unlike terms 18. 2x+5 19. A. 4t; 5t; 3t; B: 12t; C. 2 miles 20. Student B; Student A translated it into an expression using a quotient rather than the product 21. 5.75 22. C 23. a) the resulting value is negative; b) the resulting value is positive 24. a) 1/7; b) 2/7; c) 3/7 25. A square root is a whole number 26. $530.45 27. I will grade 28. -12 29. 5(a+c) + (14a+8c); 19a + 13c 30. 4/52= 1/3; 3/51=1/17 • -8m • 2 • -13 • 10 • 7(X+(-5)) • 3X+12 • Community Property of Addition • False; the answers are actually inverses of each other. • -3 • Student B; Student A should have subtracted 1/3 from both sides of the equation to isolate x. • C • 52.05 • 3500-x= 1278; 2222 • Add 2.5 to both sides of the equal sign

  4. Glossary • Coordinate Plane: an x-axis and y-axis that intersect to create 4 quadrants. • Origin: the intersection point of the x and y axis • Ordered pair: a point on a coordinate plane • X-coordinate: the distance to the right or left of the origin • Y-coordinate: the distance above or below the origin • Independent variable: the variable whose value can be chosen. Also called the input variable • Dependent variable: the variable whose value is determined by the input value. Also called the output value.

  5. Warm up Objective I will be able to plot ordered pairs using an ordered point. Notes

  6. Warm up Objective Graphing pairs on a Coodinate Plane . b.) (-3,0) Notes

  7. White Boards Ex. 2: Identifying Independent and Dependent Variables a.) b) Electric bill total, kilowatts of electricity used Notes

  8. Ex. 3: Determining the dependent variable Y=4x+2 Notes

  9. Ex. 4: Real World The federal minimum wage is about $5 per hour. The total on a minimum wage worker’s paycheck is dependent on the number of hours worked. The paycheck total can be calculated using the equation y=5x Notes
