For which value of x is undefined?
Answers
In this one, there's a fraction, and you're asked: "When is the fraction undefined ?"
If the denominator of the fraction is ever zero, then that's nothing but the old
"division by zero", which is forbidden, not permitted, and undefined.
The denominator of the fraction is x² + 3x + 2 . Can that ever be zero ?
It might be easier to see if you factor it:
(x + 2) · (x + 1) = 0
This equation is true if x=-2 OR x=-1 .
Either way, the denominator of the fraction is zero.
So those are the values of 'x' for which the fraction is undefined.

Answer:
2108
Step-by-step explanation:
First find the hours between 9 am and 5 pm
8 hours
This is at her regular rate of 136
8*136 = 1088
Then between 5 pm and 10 pm = 5 hours
This is at 1.5 her regular rate 1.5*136 =204
5 *204 =1020
1088+1020 = 2108
$136 x 1.5 = $204 ( 5pm - 11 pm)
9-5pm = 8 hrs
5-10 = 5 hrs
(136 x 8) + (204 x 5)
$1088 + $1020
= $2108

(x - x)² + (y - y)² = d² Distance formula
(4 + 5)² + (-7 - 9)² = d² Substitute the given values; make sure to always subtract in the same direction (for example, if you had (1, 2) and (3, 4), if you start by subtracting 1 - 3, then subtract 2 - 4 again, not 4 - 2); also remember that when you subtract a negative, you add
9² - 16² = d² Add; remember that when you subtract a positive from a negative, the answer is negative (-7 - 9 = -16), but this doesn't really matter since we're about to square it anyway
81 + 256 = d² Square both numbers; you can use a calculator for this, if you want
337 + d² Add
d = √337 Take the square root of both sides to cancel out the exponent
So, the distance is √337. You can use a calculator to get the estimated answer, which is about 18.4
