Question

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

Answer 1

Answer:

The correct answer is -44

Step-by-step 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

Answer:

-44

Step-by-step 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
