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

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

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

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

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

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

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

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

Product rule<br> G(x)=(2x+1)(x^3-1)

Andrej [43]

Answer:

2x^4 + x^3 - 2x -1

Step-by-step explanation:

Do each one at a time and add them after you are done is necessary, first multiply 2x times x^3 this gives 2x^4. Then multiply 1 times x^3 to get x^3. Then multiply 2x times -1 to get -2x. Then multiply -1 and +1 to get -1. Then combine them together. None of the terms are like terms so you don't need to worry about combining them further but keep that in mind for other problems. The final answer becomes 2x^4 + X^3 - 2x -1 because none of the terms are the same power.

A researcher is selecting lab rats for her experiment. She assigns each rat a number and picks numbers out of a hat while blindf

laiz [17]

Answer: $\dfrac{76}{89}$

Step-by-step explanation:

The pool of rats from which the researcher is drawing participants is composed of the following:

23 male albino rats

21 male spotted rats

35 female albino rats

11 female spotted rats

Total rats = 23+21+35+11 =90

$P(male\ albino)=\dfrac{23}{90}$

After drawing first rat , total rats remained = 89

$P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}$

The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = $\dfrac{76}{89}$
