Which of the following equations will produce the graph shown below?
melisa1 [442]
The graph is a circle, centered at the origin, with radius=4.

We know that we can write the equation of a circle with radius r and center (a,b) as :

                      (x-a)^2+(y-b)^2=r^2.

Thus, substituting (a, b) with (0, 0) and r with 4, we have:

                      x^2+y^2=16.

The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:

x^2+y^2=16\\\\x^2+y^2-16=0\\\\2(x^2+y^2-16)=0, 

we would still have the same roots.

Thus, the equation of the circle can be written as :

                                    2x^2+2y^2=32.

Eva8 [605]
5 out of 20 like Star Wars so what value (x) should like Star Wars out of 200. Set up a proportion comparing the two.

x= # of people in 7th gr who like Star Wars

5/20= x/200
cross multiply

(5*200)= (20*x)
1000= 20x
divide both sides by 20

50= x


ANSWER: 50 people in the 7th grade should like Star Wars.

Hope this helps! :)
