Which property of addition is shown below? if x = 1 + 2i and y = –1 – 2i, then x + y = 0

Additive inverse property is satisfied in the given question

Explanation:

We have been given with two complex numbers  x=1+2i and  y= -1 -2i

we can clearly see that y is additive inverse of x

Since, additive inverse of the complex number is -(a+ib)

Where a and b are real numbers

Here in given numbers a=1 and b=2i

sum of number and its additive inverse is zero.

i dont know

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
