if x = -5; then |x - 7| =
The positive answer to subbing in |-5 - 7|
Remember that absolute value is the positive solution.
It might help to think about what an absolute value graph looks like :)
is the answer 12?
To find the value of |x - 7| when x = -5, we substitute the value of x into the expression |x - 7| and evaluate it.
|x - 7| = |-5 - 7|
First, we simplify the expression inside the absolute value brackets.
|-5 - 7| = |-12|
Next, we evaluate the absolute value of -12. The absolute value of a number is always its distance from zero on the number line, so |-12| = 12.
Therefore, when x = -5, |x - 7| = 12.
