What does the equation -9+|m-8|<0 equal to?

UNO [17]

The equation $-9+|m-8|$ equals to $-1 < m < 17$

Step-by-step explanation:

We need to solve the equation:

$-9+|m-8|$

Solving:

Adding 9 on both sides

$-9+9+|m-8|$

Applying absolute rule: |u| < a and a > 0 then, -a < u < a

So, $-9 < m-8 < 9$

Now we have,

m-8>-9 and m-8 <9

m>-9+8 and m <9+8

m>-1 and m<17

Combining the intervals:

-1 < m < 17

So the equation $-9+|m-8|$ equals to $-1 < m < 17$
