Modeling Two-Step Inequalities
You can use algebra tiles to model two-step inequalities.
Use algebra tiles to model 2k +52-3.
A Using the line on the mat, draw in the
inequality symbol shown in the inequality.
B How can you model the left side of the
inequality?
How can you model the right side of the inequality?
D
Use algebra tiles or draw them to model the inequality on the mat.

1. Multiple Representations How does your model differ from the one
you would draw to model the equation 2k + 5 = -3?

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

could you reply to this with the question so i can ?

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
