*20-21 One-step Inequalities (addition & subtraction)

Solve one-step inequalities with addition & subtraction! Practice graphing & testing solutions.

Test each number to decide if the number is a solution for the inequality.n + 3 < 9 SOLUTION n = 4 n = 5 NOT A SOLUTION n = 6 n = 7 Test each number to decide if the number is a solution for the inequality.n + 3 ≥ 9 SOLUTION n = 6 n = 7 NOT A SOLUTION n = 4 n = 5 What would you do to both sides of the inequality to solve it? n - 5 > 9 + 9 to both sides + 5 to both sides - 9 from both sides - 5 from both sides What would you do to both sides of the inequality to solve it? n + 3 < 5 + 3 both sides + 5 both sides - 3 both sides - 5 both sides Which set of numbers are TRUE for the inequality? n + 3 < 5 - 2, - 1, 0, 1 - 1, 0, 1, 2 2, 3, 4, 5 3, 4, 5, 6 Look at the graph. Choose the set of numbers and the inequality that is true. n + 2 > 43, 4, 5, 6 n - 2 > 47, 8, 9, 10 n + 2 < 4- 1, 0, 1, 2 n - 2 < 42, 3, 4, 5 Which graph represents the inequality? n - 5 < - 2 Which graph represents the inequality? n - 9 > - 6 Match each inequality to the "flipped" inequality. n n n n n > - 5 - 5 5 5 Which graph represents the inequality?8 > n + 2
