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

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
