Juan piensa en un número si al doble del número le aumenta 18 encuentra que es igual a 27, cual es el número?​

Step-by-step explanation:

el número es 4,5

es una ecuación lineal:

2x+18=27

2x=9

x=9/2

x=4,5

el numero es 4.5

Step-by-step explanation:

numero = X

Doble del numero = 2X

entonces

2X + 18 =27

2x = 27 - 18

2X = 9

x = 9/2

x = 4.5

Usé el traductor de Go ogle para esto, ¡así que lo siento si no tiene sentido!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
