First, plug in 5 for x:

| -5 * 5 + 12 | = |-25 + 12| = |-13|

Those two lines are absolute value, which measures the distance from the number to 0 on a number line. This distance is always positive.

The distance from -13 to 0 on a number line is 13. The answer is 13.

Absolute value returns the positive value of an expression.

The value of [tex]|-5x + 12|[/tex] is 13

The expression is given as:

[tex]|-5x + 12|[/tex]

Where:

[tex]x = 5[/tex]

Substitute 5 for x in [tex]|-5x + 12|[/tex]

[tex]|-5x + 12| =|-5 \times 5 + 12|[/tex]

Evaluate the multiplication

[tex]|-5x + 12| =|-25 + 12|[/tex]

Add -25 and 12

[tex]|-5x + 12| =|-13|[/tex]

Remove absolute bracket

[tex]|-5x + 12| = 13[/tex]

Hence, the result of the expression is 13
