For what values of a are the following expressions true? |a–5|=5–a
Using the definition of the absolute value function, it is found that this expression is true for all values of a.
It measures the distance from a point x to the origin, hence if:
\(|f(x)| = x\)
It means that:
\(f(x) = x\) or \(f(x) = -x\)
In this problem, the expression is:
|a - 5| = 5 - a
Hence:
a - 5 = 5 - a
2a = 10
a = 5
a - 5 = -5 + a
0 = 0
Hence, this expression is true for all values of a.

The expression is true for all values of a between 0 and 5 (inclusive)
The expression is given as:
|a–5|=5–a
The absolute value expression is always positive.
So, we have:
a - 5 = 5 -a or 5 - a = 5 - a
For the expression a - 5 = 5 -a, we have:
a + a = 5 + 5
Evaluate like terms
2a = 10
Divide both sides by 2
a = 5
For the expression 5 - a = 5 - a, we have:
0 = 0
So, we have:
0 = 0 or a = 5
This means that, the expression is true for all values of a between 0 and 5 (inclusive)
