Answer:
Simplifying
X + -4 = 2x
Reorder the terms:
-4 + X = 2x
Solving
-4 + X = 2x
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X = 4 + 2x
Combine like terms: -4 + 4 = 0
0 + X = 4 + 2x
X = 4 + 2x
Simplifying
X = 4 + 2x
Step-by-step explanation:
First, plot the y-intercept, which is (0,1).
Next, put your pencil point at this y-intercept (0,1). Move it 1 space the right and from there 2 spaces up. Plot this new point.
Last, draw a line thru the two points you plotted.
Qualitative has to do more with your senses, and quantitative is more about numbers. Quantitative would be something like the volume is 25.5 mL, but the liquid being blue would be qualitative since it has no numbers
$499.96 x .15 = $74.99 off
$499.96 - $74.99 = $451.98
Hope this helps you!
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
