6 0

Answer:

P'(1, 5)

Step-by-step explanation:

Up 3 is vertical movement, so it changes the y-value: 2 + 3 = 5

Right 4 is horizontal movement, so it changes the x-value: -3 + 4 = 1

What value of w is a solution to this equation? w/2 = 6 w = 10 or w = 12

Monica [59]

W=12 would be the correct answer. I got this because if you divided 12 by 2, (12/2) you would get 6!

A square has side length of 9 in. If the area is doubled, what happens to the side length?

Alika [10]

Answer:

The side length is multiplied by $\sqrt{2}$

Step-by-step explanation:

we know that

The area of the original square is equal to

$A=9^{2}=81\ in^{2}$

If the area is doubled

then

The area of the larger square is

$A1=(2)81=162\ in^{2}$

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the larger square

y ---> the area of the original square

$z^{2}=\frac{x}{y}$

we have

$x=162\ in\^{2}$

$y=81\ in\^{2}$

$z^{2}=\frac{162}{81}$

$z^{2}=2$

$z=\sqrt{2}$ ------> scale factor

therefore

The side length is multiplied by $\sqrt{2}$

Soit trois nombres consécutifs. Lorsque l’on soustrait le double du deuxième nombre du quadruple du

irina [24]

Answer:

Les trois nombres sont 5, 6 et 7.

Step-by-step explanation:

Soit x le premier nombre.

x + 1 sera le second et x + 2 sera le troisième.

On pose l'équation :

2x + 3(x + 1) = 4(x + 2)

2x + 3x + 3 = 4x + 8

5x - 4x = 8 - 3

x = 5
