Unit 2 equations and inequalities homework 8 answer key

By the end of this unit, students will be able to:

  • Explain if a value from a set makes an inequality or equation true/false (EE.5)
  • Write an expression or equation using a variable in order to solve a real world problem (EE.6)
  • Solve real world and mathematical problems by evaluating an expression or equation when the variable is a positive rational number (EE.7)
  • Write an inequality about a real-world situation and recognize that it has infinite solutions and graph that inequality on a number line (EE.8)
  • Write an equation involving dependent and independent variables and evaluate that equation (EE.9)
