Answer:
-3 -3x
Step-by-step explanation:
12−3∙(5+x)
simplify
12 - 3(5) + -3(x)
12 - 15 - 3x
-3 - 3x
I believe it would be -4/3.
Answer:
The general limit exists at <em>x</em> = 9 and is equal to 300.
Step-by-step explanation:
We want to find the general limit of the function:

By definition, a general limit exists at a point if the two one-sided limits exist and are equivalent to each other.
So, let's find each one-sided limit: the left-hand side and the right-hand side.
The left-hand limit is given by:
<h3>

</h3>
Since the given function is a polynomial, we can use direct substitution. This yields:

Evaluate:

Therefore:

The right-hand limit is given by:

Again, since the function is a polynomial, we can use direct substitution. This yields:

Evaluate:

Therefore:

Thus, we can see that:

Since the two-sided limits exist and are equivalent, the general limit of the function does exist at <em>x</em> = 9 and is equal to 300.
