Question

Evaluate – la – 3b| a = -2 and b = 6.

Answer 1

-l -2-18l=-l-20l=-20

Answer 2

`\boxed{-20}`

.

Explanation:

Absotule value

`|x| = x` if
`x \geq 0`

`|x| = -x` if
`x < 0`

.

a = -2

b = 6

So

`-|a - 3b|`

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

`= -|-2 - 18|`

`= -|-20|`

`= - (-(-20))`

`= -(20)`

`= -20`

.
