Answer:

no, the answer is 10 because they are supplementary lines which equal to 180. So basically 10 takes the place of X when your doing the equation. (shown below) vvvv

Step-by-step explanation:

DE= 8x + 20

EC= 3x + 50

DE= 8(10) +20=100

EC= 3(10) + 50=80

100+80=180

X=10

Find the domain of the rational expression: x-3/2x-8

miss Akunina [59]

Answer:

$\huge\boxed{x\neq4\to x\in\mathbb{R}\backslash\{4\}}$

Step-by-step explanation:

$\dfrac{x-3}{2x-8}$

We know: the denominator must be different than 0.

Therefore

$2x-8\neq0$ <em>add 8 to both sides</em>

$2x-8+8\neq0+8$

$2x\neq8$ <em>divide both sides by 2</em>

$\dfrac{2x}{2}=\dfrac{8}{2}\\\\x\neq4$

Which value below will make 3-6x=21

Lorico [155]

We are given the following equation and want to find which value of x will make it true:

$3-6x=21$

Subtract 3 from both sides

$-6x=18$

Divide both sides by -6

$x=-3$

Thus, the value that will make 3-6x=21 is x=-3. Let me know if you need any clarifications, thanks!
