4 8th Grade Topic 1 Question / Why can absolute value equations have more than one solution or no solution?

5 8th Grade Topic 1 Answer / The expression inside the absolute value symbols can be either positive or negative. This would give you more than one answer. / If the problem has no solution it is because it has a negative answer. Absolute value is NEVER equal to a negative value, so the problem does not have a solution. / The expression inside the absolute value symbols can be either positive or negative. This would give you more than one answer. / If the problem has no solution it is because it has a negative answer. Absolute value is NEVER equal to a negative value, so the problem does not have a solution. Return

6 8th Grade Topic 2 Question / What steps do you take when solving multi-step equations?

7 8th Grade Topic 2 Answer / Combine Like Terms On Each Side of the Equal Sign / Solve by using rules for one- or two- step equations / Combine Like Terms On Each Side of the Equal Sign / Solve by using rules for one- or two- step equations Return

8 8th Grade Topic 3 Question / What is the rule for multiplying or dividing with a negative in an inequality problem?

9 8th Grade Topic 3 Answer / When you multiply or divide an inequality with a negative number, you must change the direction of the inequality symbol. Return

10 8th Grade Topic 4 Question / What are possible solutions of inequalities?

11 8th Grade Topic 4 Answer / The answer will be a range of answers graphed on a number line called an interval. Return

12 8th Grade Topic 5 Question / How can I tell the difference between an expression, an equation, and an inequality?

13 8th Grade Topic 5 Answer / An expression doesn’t have a given value. Example: 3x - 8 / An equation has a given value shown with an equal sign. / Example: 3x - 8 = -5 / An inequality has a range of answers. Example: 3x - 8 < 5, x <4, so any number less than 4 would be a correct answer to the inequality. / An expression doesn’t have a given value.

Example: 3x - 8 < 5, x <4, so any number less than 4 would be a correct answer to the inequality. Return

14 8th Grade Topic 6 Question / How can absolute value be represented on a number line?

15 8th Grade Topic 6 Answer / You would graph both answers on a number line, positive and negative.

16 8th Grade Topic 7 Question / When graphing absolute value equations on a coordinate plane, how can you tell if you answers are correct?

17 8th Grade Topic 7 Answer / Whenever you have an absolute value graph, the general shape will be a “v” or an upside down “v”. Return

18 8th Grade Topic 8 Question / To ride the Superman Roller Coaster at Six Flags, you must be at least 4 feet or taller. Represent this with a variable.

19 8th Grade Topic 8 Answer / X ≥ 4 Return

20 8th Grade Topic 9 Question / Solve the following inequality: -2x - 5 ≥ 7 / Solve the following inequality: -2x - 5 ≥ 7

21 8th Grade Topic 9 Answer / X ≤ -6 Return

22 8th Grade Topic 10 Question / Solve the following problem: / 5 = |x + 2| + 8 / Solve the following problem: / 5 = |x + 2| + 8

23 8th Grade Topic 10 Answer / Answer: No solution because the value would be negative and abolute value does not give negative answers. Return

24 Million Dollar Question Grade Level Topic 11 Making the Grade

25 1,000,000 Question / Your math teacher says the grades, g, in your class can be represented by the inequality: |g - 85| ≤ 10. What is the lowest grade and the highest grade in the class? / Your math teacher says the grades, g, in your class can be represented by the inequality: |g - 85| ≤ 10. What is the lowest grade and the highest grade in the class?

26 1,000,000 Answer / Lowest Grade-75 / Highest Grade-95 / Lowest Grade-75 / Highest Grade-95 Return
