Answer:
see below
Step-by-step explanation:
We know that the center is (0,0) and the radius is |3 - 0| = 3.
Standard form of a circle: (x - h)² + (y - k)² = r² where (h, k) is the center and r is the radius. Plugging in h = 0, k = 0 and r = 3 gives us x² + y² = 9.
Answer: ![70a+21b](https://tex.z-dn.net/?f=70a%2B21b)
Step-by-step explanation:
By definition, equivalent expressions have the same value but they look different.
In order to solve this exercise you need to remember:
1) The multiplication of signs:
![(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-](https://tex.z-dn.net/?f=%28%2B%29%28%2B%29%3D%2B%5C%5C%28-%29%28-%29%3D%2B%5C%5C%28-%29%28%2B%29%3D-%5C%5C%28%2B%29%28-%29%3D-)
2) According to the Distributive property:
![a(b+c)=ab+ac\\\\a(b-c)=ab-ac](https://tex.z-dn.net/?f=a%28b%2Bc%29%3Dab%2Bac%5C%5C%5C%5Ca%28b-c%29%3Dab-ac)
In this case you have this expresion:
Then, in order to find an equivalent expression to
you need to simplify it applying the Distributive property (Remember that you must multiply each term inside the parentheses by 7)
Therefore, through this procedure you get the following equivalent expression that shows the sum of exactly two terms:
![7(10a+3b)=(7)(10a)+(7)(3b)=70a+21b](https://tex.z-dn.net/?f=7%2810a%2B3b%29%3D%287%29%2810a%29%2B%287%29%283b%29%3D70a%2B21b)
Answer: Each person pays 33 dollars.
Step-by-step explanation: If the group pays 264 dollars and we assume each person pays the same we divide 264/8 to get 33 dollars per person.
