(x+3)^2+(y-1)^2=18
x and y always lie and you must square 9

The answer is 1 or A.

(x-h)^{2}+ (y-k)^{2}= r^{2}

(x+3)^{2}+ (y-1)^{2}=81

What is 1/6x=4 in solving equations with rational coefficients
Debora [2.8K]
To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

\frac{1}{6}x =4 The reciprocal of 1/6 is 6/1 or 6
6( \frac{1}{6} x)= 6(4)  The product of reciprocals equals 1 
1x = 24
x = 24

Use complete sentences to describe why it is valid to say that both a function and its inverse describe the same relationship.
Serhud [2]

Answer:

Step-by-step explanation:

A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse. 

Looking at ordered pairs of the function and its inverse would look like this:

(2,4) on the original function becomes (4,2) on the inverse. 

While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x. 

So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y

I hope this helped you because i barley understood this myself.

A Honda Element with a dealer invoice price of $19,700 was retail priced at $23,000 how much is the approximate percent markup b
-BARSIC- [3]
So the mark up is 23,000-19,700 = 3,300

To figure of what the percent of markup is based on the SELLING price:

3,300/23,000 = x/100; now cross multiply and you have:
23,000x = 3,300(100)
23,000x = 330,000; isolate x by dividing both sides by 23,000, and you get x= 14.35

To check your work multiply 23,000 x 0.1435 = 3000.05, which was the approximate amount of markup
