Question

What is the value of –2|6x – y| when x = –3 and y = 4?

Answer 1

The correct answer is -44

Explanation:

Points to remember

|x| = x

|-x| = x

To find the value of –2|6x – y|

We have –2|6x – y| When x = -3 and y = 4

Substitute the value of x and y

–2|6x – y| = –2|(6 * -3) – 4|

= -2|-18 - 4|

= -2|-22|

= -2 * 22

= -44

Therefore the value of –2|6x – y| when x = -3 and y = 4

–2|6x – y|

Answer 2

-44

Explanation:

We have the expression

`-2|6x - y|`

We need to find the value of the expression when x = -3 and y = 4

Then we must replace the variable with the number -3 and the variable y with the number 4

This is:

`-2|6(-3) - (4)|`

`-2|-18 - 4|`

`-2|-22|`

Remember that the absolute value always results in a positive number.

So

`-2|-22| = -2(22)=-44`

the answer is -44
