Question 1

1.

Solve--Use inverse operations to solve the inequality (get the variable by itself).

x+3>15

List out three solutions to the inequality.

You MUST SYW in formative

CFS:
#1: Accurately solves inequality with inverse operations
#2: Accurately interprets solutions

Question 2

2.

Reverse??--Start with the given inequality, then divide both sides by -2.
Type out your new inequality.

-10<6

CFS:
#1: Accurately performs operation
#2: Accurately changes signs and symbols if necessary

Question 3

3.

Solve 2--Solve the given inequality. Type your solution set to the inequality.

Ex) x > 4

-\frac{1}{3}x>7

CFS:
#1: Accurately solves inequality with inverse operations
#2: Accurately changes signs and symbols if necessary

Question 4

4.

Solve--Use inverse operations to solve the inequality (get the variable by itself like we do for equations).

x-7<18

List out three solutions to the inequality.

CFS:
#1: Accurately solves inequality with inverse operations
#2: Accurately interprets solutions

Question 5

5.

Negatives again--Use inverse operations to solve the inequality (get the variable by itself).

-4x>24

List out three solutions to the inequality.

CFS:
#1: Accurately solves inequality with inverse operations
#2: Accurately interprets solutions

Question 6

6.

True or False?--Is 7 a solution to the inequality x≤-9 ? Explain why or why not.

"I think 7 (is / is not) a solution because..."

Question 7

7.

SPICY--Try if you have time (optional)

Solve the two-step inequality.

7x+3>45

List out three possible values of x.

CFS:
#1: Accurately solves inequality with inverse operations
#2: Accurately interprets solutions

Question 8

8.

Preserved or Reversed?--Solve the inequality.

-9x<90

List out 3 possible solutions.

CFS:
#1: Accurately solves inequality with inverse operations
#2: Accurately interprets solutions
