Question 2
2. What property of inequality can justify the math in Step 2?

Step 1:

−6(3w−7)>−66

−18w+42>−66

Step 2:

−18w+42−42>−66−42

−18w>−108

Step 3:

(−18w)−18>(−108)−18

w<6

Question 3
3. Juana, Anish, and Giselle are comparing their solutions to the inequality 56x≤−10
. Juana says that the inequality symbol must be reversed because there is a negative sign in the inequality. Anish says the Multiplication Property of Inequality or Division Property of Inequality must be applied. Giselle says the inequality symbol must stay the same.

Based on these answers, which combination of people is correct?

Sure! Here are the responses to each question based on your provided information:

Question 1:

Property of Inequality: Multiplication Property of Inequality - It allows you to multiply both sides of an inequality by a positive number without changing the direction of the inequality.

Question 2:

Property of Inequality: Subtraction Property of Inequality - It allows you to subtract the same number from both sides of an inequality without changing the direction of the inequality.

Question 3:

Combination of People Correct: Anish, Juana, and Giselle - Anish's reasoning is correct because the Multiplication or Division Property of Inequality applies when dealing with negative numbers. Juana's statement that it must be reversed is incorrect, and Giselle is also incorrect in her statement that the inequality stays the same because we need to apply the multiplication/division property when dividing by a negative.

Question 4:

Inequality represented by the number line: x<−7 - The number line shows all values less than -7 (unless there is a closed circle at -7, then it would be x ≤ -7).

Question 5:

Graph x>11: You would draw a number line and shade to the right of 11, with an open circle at 11 (indicating that 11 is not included).
