Answer:
5
Step-by-step explanation:
-5 - (-10)
Here we have to use sign of multiplication rule.
negative * negative = positive
that is, -(-) = +
We use this rule and simplify.
- (-10) = + 10
Therefore, -5 + 10
When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.
-5 + 10 = + 5
Hence, the answer is 5
Hope this is will help you.

Answer:
If x=1, then f(x)= undefined
Step-by-step explanation:
1*1=1
1-1=0
0/0
You can't divide by 0, so anything that is divided by 0 is undefined.
((1*1)-1)/(1-1)
(1-1)/(1-1)
0/0
0/0=Undefined
f(x)= undefined
