For the transformation T, what is T-1?

T : (x, y) (x + 4, y + 3)
T-1: (x, y)

A.) (x - 4, y - 3)
B.) (-4x, -3y)
C.) (x + 3, y + 2)

Respuesta :

MrZaw
A.) (x-4 , y-3)
inverse of addition is subtraction.

Answer:

The correct option is A.

Step-by-step explanation:

The transformation T is given as

[tex]T:(x,y)\rightarrow (x+4,y+3)[/tex]

Let the transformation T⁻¹ is defined as

[tex]T^{-1}:(x,y)\rightarrow (x+a,y+b)[/tex]

If T and T⁻¹ are inverses of each other, then

[tex]T(T^{-1}(x))=x[/tex]

[tex]T(x+a)=x[/tex]

[tex]x+a+4=x[/tex]

[tex]a=-4[/tex]

The value of a is -4.

If T and T⁻¹ are inverses of each other, then

[tex]T(T^{-1}(y))=y[/tex]

[tex]T(y+b)=y[/tex]

[tex]y+b+3=y[/tex]

[tex]b=-3[/tex]

The value of b is -3.

The transformation T⁻¹ is defined as

[tex]T^{-1}:(x,y)\rightarrow (x-4,y-3)[/tex]

Therefore the correct option is A.
