Y= |x−3| + |x+2| − |x−5|, if x&gt;5<br> I need to know what y equals.
olganol [36]

Answer:

y  \ge9

Step-by-step explanation:

The given function is

y =  |x - 3|   +  |x  + 2|  -  |x - 5|

By the triangle inequality property,

|x + y|  \leqslant  |x|  +  |y|

and the alternate triangle inequality property;

|x - y|  \geqslant  |x|  -  |y|

We apply this property to get:

y  \geqslant   |x |    - |3|    +  |x |  +  |2|  -(  |x |  -  |5| )

Expand parenthesis to get:

y  \geqslant   |x |    - |3|    +  |x |  +  |2|  - |x |   +   |5|

Simplify to get:

y  \geqslant   |x |    - 3+  |x |  +  2- |x |   +   5

Group similar terms to get:

y  \geqslant   |x |  +   |x | - |x |    - 3 + 2+   5

y  \geqslant   |x |   + 4

When x>5,

y  \geqslant   |5 |   + 4

That's;

y  \geqslant   5  + 4   \\ y  \geqslant   9
