12-2x = -2(y-x) please explain how you got the answer

abruzzese [7]

Answer: $x=\frac{y+6}{2}$

Step-by-step explanation:

$12-2x=-2\left(y-x\right)$

________________________________

(Expand: $-2\left(y-x\right)$ )

$=-2y-\left(-2\right)x$

$=-2y+2x$

_________________________________

$12-2x=-2y+2x$

$-2x=-2y+2x-12$

$-2x-2x=-2y+2x-12-2x$

$-4x=-2y-12$

$\frac{-4x}{-4}=-\frac{2y}{-4}-\frac{12}{-4}$

__________________________________

(Simplify: $\frac{-4x}{-4}$ )

$\frac{-4x}{-4}$

$=\frac{4x}{4}$

$=x$

__________________________________

(Simplify: $-\frac{2y}{-4}-\frac{12}{-4}$ )

$=\frac{-2y-12}{-4}$

$-\frac{-2y-12}{4}$

$\frac{-2y-12}{4}$

$=-\frac{y+6}{2}$

$-\left(-\frac{y+6}{2}\right)$

$=\frac{y+6}{2}$

$x=\frac{y+6}{2}$

List the domain and range of (5,12)(3,-3),(-2,7)(2,12)(5,1)

Sliva [168]

Answer:

Domain={-2,2,3,5}

Range={-3,1,7,12}

Step-by-step explanation:

The given ordered pairs are (5,12)(3,-3),(-2,7)(2,12)(5,1).

The domain refers to the set of all the first coordinates(x-values).

Domain={-2,2,3,5}

The range refers to the set of all the second coordinates (y-values).

Range={-3,1,7,12}

Note that, we do not repeat elements in a set.

Do not list the 5 in the domain twice.

The same applies to the 12 in the range
