They don't need to be pure real or imaginary. Any "mixed" complex number works so long as .
Let . Then
so .
The geometric interpretation is essentially identical. is a complex number twice the distance away from the origin in the complex plane as , which is exactly .

the ratios of the outputs for inputs that are 1 apart is
ratio = = = = 2
This is also true for the fractional outputs

Answer:
(b) T(x, y) -> (x-3, y-6)
Step-by-step explanation:
Each image point is 3 left and 6 down from the corresponding pre-image point. That is -3 is added to each x-value, and -6 is added to each y-value. That transformation is represented by ...
T(x, y) ⇒ (x-3, y-6)
Answer:
entonces el número es 79
Step-by-step explanation:
Como es un número de dos dígitos, tiene la forma; 10x + y.
De la primera declaración;
[(10x + y) -17] / (x + y) = 5
10x + y-17 = 5 (x + y)
10x + y-17 = 5x + 5y
10x -5x + y-5y = 17
5x -4y = 17 ••••••• (i)
Ahora pasemos al segundo conjunto de instrucciones;
Tenga en cuenta que y es el número de dígito.
[(10x + y) -2] / (y-2) = 19
10x + y-2 = 19 (y-2)
10x + y -2 = 19y -38
10x + y-19y = -38 + 2
10x-18y = -36 •••••••• (ii)
Entonces resolvemos ambas ecuaciones simultáneamente Multiplica la ecuación i por 2 y ii por 1, luego resta ii de i
10x -8y = 34
10x -18y = -36
Restando; tenemos 10 años =
70 y = 70/10 = 7
Para obtener x, sustituya y = 7 en la ecuación i
5x -4 (7) = 17
5x -28 = 17
5x = 17 + 28 5x = 45
x = 45/5 x = 9
entonces el número es 79
