Answer:

PEMDAS

Step-by-step explanation:

Using PEMDAS or the order of operations, you first multiply 2 by 6

2-2×6+3

2-12+3

Then you can go in any order since addition and subtraction take the same precedence.

-10+3=-7

2y = x + 10 3y = 3x + 15

ExtremeBDS [4]

{2y = x + 10
{3y = 3x + 15 |:3

{2y = x + 10
{y = x + 5

{2(x+5) = x + 10
{y = x + 5

{2x+10 = x + 10
{y = x + 5

{2x - x = 10 - 10
{y = x + 5

{x = 0
{y = x + 5

{x = 0
{y = 5

Which of the following is an example of a complex number that is not in the set of real numbers?

ExtremeBDS [4]

A complex number has a real and an imaginary part

$4 + 9i$ is a complex number

A complex number is represented as:

$a + bi$

Where:

$a \to$ real

$bi \to$ imaginary

By comparing the options to $a + bi$ ;

$-7$ and $2 + \sqrt 5$ are not complex numbers

This is so because they do not have imaginary parts

However,

$4 + 9i$ is a complex number

Because; 9i is imaginary
