Answer:
1.42
Step-by-step explanation:
<span>increases, the value of the inverse variable will decrease at the same rate and vice versa. The only time in which these two inverse variables will have the same value is when they each have a value of zero.</span>
Answer: (x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.
Step-by-step explanation:
Factor the numerator:
(x+9)(x-5)
Factor the denominator:
(x+1)(x+9)
So you have
(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?
You're left with (x-5)/(x+1)
The only number that is restricted is -1, because that would make the denominator zero, which is a no no!!
Answer:
x > 8
Explanation:
−2x + 12 < −4
[<em> Subtract 12 from both sides </em>]
−2x + 12 − 12 < −4 − 12
−2x < −16
[ <em>Divide both sides by -2 </em>]
-2x / -2 < -16 / -2
x > 8
