<span>Let x = # of rides
Plan A: 10 + 3x
Plan B: 20 + x
if x < 5 rides then plan A is better buy
if x = 5 both plans are the same
if x > 5 then plan B is the best buy
Prove:
x = 6 (rides)
plan A: </span>10 + 3x = 10 + 3(6) = 10+18 = $28
plan B: 20 + x = 20 + 6 = $26
1 file + 3 pens = $32.85 --------------- (1)
2 files + 8 pens = $83.50 ----------------(2)
(1) x 2 :
2 files + 6 pens = $65.70 ----------------(1a)
(2) - (1a) :
2 pens = $17.80
1 pen = $8.90
-------------------------------------------------------------------------------
Answer: One pen costs $8.90.

Answer:
Option A and Option B are not equivalent to the given expression.
Step-by-step explanation:
We are given the following expression:

Applying properties of exponents and base:

A. Using the exponential property
, we can write:

which is not equal to the given expression.
B. Using the exponential property
, we can write:

which is not equal to the given expression.
C. First we convert the radical form into exponent form. Then by using the property
of exponent, we can write the following:

which is equal to the given expression.
D. First we convert the radical form into exponent form. Then by using the property
of exponent, we can write the following:

which is equal to the given expression.
Option D and Option C are equivalent to the given expression.

And replacing we got:

Answer:
y = -2
Step-by-step explanation:
Any asymptotes of a rational function will be described by the quotient of the numerator and denominator (excluding any remainder).

The horizontal asymptote is ...
y = -2
