Basically you canceling out and your answer is R= 1/2
DIA [1.3K]3 years ago

Remember that to add/subtract fractions you need a common denominator...

3/(r-2)+1/r=0  so we need r(r-2) as the common denominator...

3r/(r(r-2))+(r-2)/(r(r-2))=0  we can cancel out the r(r-2) by multiplying the whole equation by it leaving us with:

3r+r-2=0 combine like terms

4r-2=0  add 2 to both sides

4r=2  divide both sides by 4

r=1/2

andrezito [222]

Answer:

The minimum number of words left to write is 215

Step-by-step explanation:

Let

w -----> the number of words left to write

we know that

The number of words left to write plus the words written so far must be greater than or equal to 500 words

Remember that the word "at least" means "greater than or equal to"

so

w+285\geq 500                

Solve for w                        

Subtract 285 both sides        

w\geq 500-285\\w\geq 215

The minimum number of words left to write is 215

For the given functions f and g find f•g and state it’s domain<br> f(x) = 3x - 6; g(x) = 8x +4
o-na [289]

f.g and its domain is 24x²-36x-24; all real numbers.

Given, f(x) = 3x - 6; g(x) = 8x +4.

We need to find the value of f.g

<h3>What is a domain?</h3>

The domain of a function; In mathematics, the domain of a function is the set of inputs accepted by the function.

Now, (f.g)(x)=(3x-6)(8x+4)

=24x²-48x+12x-24

=24x²-36x-24

Therefore, f.g and its domain is 24x²-36x-24; all real numbers.
