Simplify the rational expression. state any excluded values. 4x - 4/ x - 1
grin007 [14]
We need to simplify this expression:

\frac{4x-4}{x-1}

So, we will call this expression as:
f(x) = \frac{4x-4}{x-1}

We can write this equation like this:

f(x) = \frac{4(x-1)}{(x-1)}

So, if we simplify it, this can be written like this:

f(x) = 4 but given that the denominator can't be zero, then:
x-1 \neq 0 ∴ x \neq 1 

Therefore:
f(x) = 4 if and only if x \neq 1

A store sold a case of scented candles for $17.85 that had been marked up 110%. What was the original price?
cestrela7 [59]
Let the letter o represent the original price.

17.85 = o + (o*1.10)
17.85 = 2.10 * o
o = 17.85/2.10=8.5
The original price was $8.50

Convert the polar equation r = 2 costheta in Cartesian equation form.
iris [78.8K]

Answer:

To transform from polar coordinates  into Cartesian coordinates  we have:

x = r x cos(theta)

y = r x sin(theta)

r^2 = x^2 + y^2

=>   r = 2*cos(theta)

<=> r = 2*(x/r)

<=> 2x = r^2

<=> 2x  = x^2 + y^2

Hope this helps!

:)
