Writing & Graphing Inequalities
Learn to write and graph inequalities! Solve word problems and match inequalities to their graphs.
#1 Match the sign to its meaning. x is equal to 9 x = 9 x is less than 9 x 9 x is greater than or equal to 9 x ≥ 9 #2 Only children whose age is under 5 years old can go on the teacup ride at the park. Which list of numbers includes ONLY numbers that are true? 1, 2, 3, 4, 5 1, 2, 3, 4 5, 6, 7, 8 6, 7, 8, 9 #3 Only children whose age is under 5 years old can go on the teacup ride at the park. Which inequality represents this situation? a > 5 a < 5 a ≥ 5 a ≤ 5 #4 School will open on time if the temperature is greaterthan - 2 degrees. Which list of numbers includes only numbers that are true? - 1, 0, 1, 2 - 5, - 4, - 3 - 2, - 1, 0, 1 - 5, - 4, - 3, - 2 #5 School will open on time if the temperature is greater than - 2 degrees. Which inequality represents this situation? t > -2 t < -2 t ≥ -2 t ≤ -2 #6 Children whose age is 6 years old and under get a special price at the buffet. Which list of numbers includes only numbers that are true? 2, 3, 6, 7 6, 7, 8, 9 4, 5, 6, 7 3, 4, 5, 6 #7 Children whose age is 6 years old and under get a special price at the buffet. Which inequality represents this situation? a > 6 a < 6 a ≥ 6 a ≤ 6 #8 You must be at least 18 years old to vote for president. Which inequality represents this situation? a > 18 a < 18 a ≥ 18 a ≤ 18 #9 The values of x are shown in blue; Which inequality matches the graph? x is less than 4 x is greater than 4 x is less than or equal to 4 x is greater than or equal to 4 #10 Which inequality matches the graph? x is less than 6 x is greater than 6 x is less than or equal to 6 x is greater than or equal to 6 #11 Which inequality matches the graph? x ≤ 6 x ≥ 6 x < 6 x > 6 #12 Match each inequality to the matching flipped inequality (meaning, which inequality statements have the same meaning?) Consider: "4 is less than 6" can also be represented as "6 is greater than 4" x > 8 8 x x ≥ 8 8 ≤ x x ≤ 8 8 ≥ x #13 Which solution below would work for x in the inequality -3x > 18 -6 -7 -5 6 7 5 #14 Which solutions below would work for x in the inequality. THERE are TWO correct answers for this question!!! -3x ≥ 18 -6 -7 -5 6 7 5
