Faz it cosi

6 -4x = -20 -10x

10x -4x = -20 -6

6x = - 26

x = -26/6

x = -13/3

spero ti ajutare

To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that
$4x + 20 = 3x + 55$
we can subtract twenty from each side
$4x + (20 - 20) = 3x + (55 - 20)$
$4x = 3x + 35$
now we can subtract like terms
$4x - 3x = (3x - 3x) + 35$
so we can get the final answer as
$1x = 35$

A 2X2 square is centered at the origin. It is dilated by a factor of 3. What are coordinates of the vertices of the square?

Vesna [10]

Answer:

The vertices are:

A' = (-3, -3)

B' = (3, -3)

C' = (3, 3)

D' = (-3, 3)

Step-by-step explanation:

Given:

A 2 x 2 square is centered at the origin.

So, the center of the square is (0, 0)

Since it is 2 x 2 square, the side of the square is 2 units.

So, the vertices of the 2 x 2 square are A (-1, -1), B(1, -1), C(1. 1), D(-1, 1)

The above square is dilated by a factor of 3.

Let's name the dilated square A'B'C'D'

To find the coordinates of the vertices of dilated square, we need to multiply each vertices of ABCD by 3.

A(-1, -1) = 3(-1, -1) = A'(-3, -3)

B(1, -1) = 3(1, -1) = B'(3, -3)

C(1, 1) = 3(1, 1) = C'(3, 3)

D(-1, 1) = 3(-1, 1) = D'(-3, 3)
