Hope that helped! :)
The sum or difference modeled by the algebra tiles is (-x^2 + 2x + 3) + (-x^2 - 2x - 1) = -2x^2 + 2
<h3>How to determine the sum or difference is modeled by the algebra tiles?</h3>
The tiles that complete the question are added as an attachment
From the attached tiles, we have:
Red tiles = -x^2 + 2x + 3
Blue tiles = -x^2 - 2x - 1
Evaluate the difference
Difference = (-x^2 + 2x + 3) - (-x^2 - 2x - 1)
This gives
(-x^2 + 2x + 3) + (-x^2 - 2x - 1) = -2x^2 + 2

Answer:

Step-by-step explanation:
In this question, we're trying to make a new equation.
We know that:
- We translated 13 units down
When it says down, we know that the y intercept would be changing.
Since there werer no y intercept or beginning point to start with, we know that before we translated, it was at 0.
Since we went down 13 units, we're subtracting 13 units from our original spot.
This means that we're going down -13.
When you put that into an equation, it should look like this:
y= |x| - 13
