INEQUALITIES / ASSIGNMENT
Find the student's error in solving the following inequality.31 < -5x + 625 < -5x-5 < x
The student should have added 6 to both sides instead of subtracting it.
The student divided 25/-5 incorrectly.
The student should have switched the direction of the inequality sign to get -5> x for a
final answer. - CORRECT ANSWER-The student should have switched the direction of
the inequality sign to get -5> x for a final answer.
Find the student's error in solving the following inequality.2 < -3x -4 < 56 < -3x < 5-2 > x
> -5/3
The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.
The student divided 6/-3 incorrectly.
The student should not have switched the direction of the sign in the final step. -
CORRECT ANSWER-The student should have added 4 to all parts (left, middle, and
right) to get 6 < -3x < 9.
Which answer choice is a solution to the inequality ?
-1
1
1.5
0 - CORRECT ANSWER-1.5
Identify the property used in each step of solving the inequality . - CORRECT
ANSWER-Step 2: Addition property
Step 3: Multiplication property
Which numbers are solutions to the inequality 2x - 1 > x + 2? Check all of the boxes that
apply. - CORRECT ANSWER-4, 5
If x < 5 and x > c, give a value of c such that there are no solutions to the compound
inequality. Explain why there are no solutions - CORRECT ANSWER-Sample response:
The value of c could be 5 or any number greater than 5.
The solution is the intersection of both solution sets of the given inequalities.
The solutions of the compound inequality must be solutions of both inequalities.
A number cannot be both less than 5 and greater than 5 at the same time.
Identify the graph of the inequality 2(2x - 1) + 7 < 13 or -2x + 5 -10. - CORRECT
ANSWER-C
