7th Math 3.12

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

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

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

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

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

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..."

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

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
