lim (-x+10)/(x©÷-100)

x¡æ10

is this correct?
1/20

I do not understand your symbols.

lim (-x+10)/(x^2-100)

as x approaches 10

is 1/20 correct

-(x-10) /[(x-10)(x+10)]

= -1/(x+10)

---> -1/20

I get -1/20 as the limit.

To find the limit of the function (-x + 10)/(x^2 - 100) as x approaches 10, we can first factor the denominator:

x^2 - 100 = (x - 10)(x + 10)

Now, let's substitute x = 10 into the function:

(-10 + 10)/(10^2 - 100) = 0/0

We obtained an indeterminate form of 0/0, which means we need to further simplify the expression.

To do that, we can factor the numerator as well:

-x + 10 = -(x - 10)

Now our expression becomes:

-(x - 10)/((x - 10)(x + 10))

We can cancel out the common factor of (x - 10) in the numerator and the denominator:

-1/(x + 10)

Now let's substitute x = 10 into this simplified expression:

-1/(10 + 10) = -1/20

So, the correct limit is -1/20, not 1/20.
