<u>2x - 3</u> = <u>2x - 4</u>
2 - x 1 - x
(2x - 3)(1 - x) = (2x - 4)(2 - x)
2x(1 - x) - 3(1 - x) = 2x(2 - x) - 4(2 - x)
2x(1) - 2x(x) - 3(1) + 3(x) = 2x(2) - 2x(x) - 4(2) + 4(x)
2x - 2x² - 3 + 3x = 4x - 2x² - 8 + 4x
-2x² + 2x - 3 + 3x = -2x² + 4x - 8 + 4x
-2x² + 2x + 3x - 3 = -2x² + 4x + 4x - 8
-2x² + 5x - 3 = -2x² + 8x - 8
<u>+ 2x² + 2x² </u>
5x - 3 = 8x - 8
<u> - 5x - 5x </u>
-3 = 3x - 8
<u>+ 8 + 8</u>
<u>-5</u> = <u>3x</u>

Answer:
in the equation y=mx+b. The equation of the line that has a slope of 0 and a y-intercept of -8 is: y=-8.
Step-by-step explanation:
If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant. If the line has an undefined slope and passes through the point (2,3) , then the equation of the line is x=2 .
You know that the y is negative and the x is positive (it's the lower right side of a graph)
Answer:
Option A.
Step-by-step explanation:
The given equation is
Liliana wants to write an equivalent expression.
It can be written as
Using commutative property, we get
![[\because A+B=B+A]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2BB%3DB%2BA%5D)
Using associative property, we get
![[\because A+(B+C)=(A+B)+C]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2B%28B%2BC%29%3D%28A%2BB%29%2BC%5D)
Using distributive property, we get
![[\because An+Bn=(A+B)n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20An%2BBn%3D%28A%2BB%29n%5D)
Using addition property, we get
Therefore, the correct option is A.
