Distance between points
D=

<span>
points are (5, 4) and (−3, −1)
</span>
D=√(-1-4)^2+(-3-5)^2
D=√25+64
D=√89
D=9.433 units
Answer:

Step-by-step explanation:
The domain of a rational function is all real numbers <em>except </em>for when the denominator equals 0.
So, to find the domain restrictions, set the denominator to 0 and solve for x.
We have the rational function:

Set the denominator to 0:

Subtract 9:

So, the domain is all real numbers except for -9.
In other words, our domain is all values to the left of negative 9 and to the right of negative 9.
In interval notation, this is:

And we're done :)
Burrito: 20
hot sauce: 80
taco: 400
(x+1)(x+2)
this is what i got hope it helps
