Answer:
asymptotes: x= -4,-2 and no holes
Step-by-step explanation:
First we need to factor the denominator of the function
y = (x-1) / (x2 + 6x + 8)
x2 + 6x + 8 = 0
delta = b2 - 4ac = 36 - 32 = 4
x1 = (-6 + 2) / 2 = -2
x2 = (-6 - 2) / 2 = -4
So we have that x2 + 6x + 8 = (x+4)(x+2)
So our function is:
y = (x-1) / (x+4)(x+2)
As there is no common expressions in the numerator and denominator, there are no holes.
The asymptotes are when the denominator is zero, so:
(x+4)(x+2) = 0
x = -4 or x = -2
-3x + 3 < 6 <em>subtract 3 from both sides</em>
-3x < 3 <em>change the signs</em>
3x > -3 <em>divide both sides by 3</em>
<h2>x > -1</h2>

Answer:
I think the better deal is $8.78.
Step-by-step explanation:
I think this because half of twenty is 10, and half of 12 is 6. The twelve pack price is closer to one dollar a can, and the 20 pack's is further. :) i hope this helps you!

Answer:
x=5.4
by comparing A and B.....u will have
7.2=4
x =3
cross multipleing
7.2*3/4=5.4
just an option
