Answer:

-3

Step-by-step explanation:

y = -2x+4y

It is given (_,-2), (x,y).

We must find the x coordinate.

Put y as -2.

(-2)= -2x+4(-2)

-2 = -2x+-8

2x = -8 + 2

2x = -6

2x/2 = -6/2

x = -3

Answer:

-3

Step-by-step explanation:

1. Plug in -2 for y, because it is the y value in the coordinates

2. Simplify -2 = -2x + 4(-2)

3.That simplifies to -2 = -2x - 8

4. Add 8 to both sides to get 6 = -2x

5. Divide both sides by -2

6. x = -3

Factor <br> (a-2b) (3x-5y) + (2b-a)(x-y)

agasfer [191]

Answer:

8by + 2ax - 4bx - 4ay

Step-by-step explanation:

I assume you mean expand so:

(a - 2b)(3x - 5y) + (2b - a)(x - y)

3ax - 5ay - 6bx + 10by + 2bx - 2by - ax + ay

Now collect like terms:

2ax - 4ay - 4bx + 8by

This is your answer but in a better order:

8by + 2ax - 4bx - 4ay

Need Help!!! ASAP

RoseWind [281]

Answer:

$P(green)+P(yellow)=\frac{3}{8}+\frac{1}{8}$

$P(green)+P(yellow)=\frac{1}{4}+\frac{1}{4}$

$P(green)+P(yellow)=\frac{3}{7}+\frac{1}{14}$

Step-by-step explanation:

The given probabilities are:

$P(red)=\frac{2}{7}$

$P(blue)=\frac{3}{14}$

Their sum is $P(red)+P(blue)=\frac{2}{7}+\frac{3}{14}$

The probabilities that will complete the model should add up to $\frac{1}{2}$ so that the sum of all probabilities is 1.

$P(green)+P(yellow)=\frac{2}{7}+\frac{2}{7}\ne\frac{1}{2}$

$P(green)+P(yellow)=\frac{3}{8}+\frac{1}{8}=\frac{1}{2}$

$P(green)+P(yellow)=\frac{1}{4}+\frac{1}{4}=\frac{1}{2}$

$P(green)+P(yellow)=\frac{5}{21}+\frac{11}{21}\ne\frac{1}{2}$

$P(green)+P(yellow)=\frac{3}{7}+\frac{1}{14}=\frac{1}{2}$

14 less than a number all divided by the same number

Fynjy0 [20]

Answer:

(n-14) / n

Step-by-step explanation:

n is your number;

"14 less" means "subtract 14", --> we have (n-14);

now we need to divide (n-14) by same number as your number, which is "n"---> final expression is: (n-14)/n
