Answer:
Hey there!
First, we want to find the radius of the circle, which equals the length of line segment AC.
Length of line segment AC, which we can find with the distance formula: , which is equal to 5.
The equation for a circle, is: , where (h, k) is the center of the circle, and r is the radius.
Although I don't know the center of the circle, I can tell you that it is either choice B or D, because the radius, 5, squared, is 25.
Hope this helps :) (And let me know if you edit the question)
Answer:
(23, 4)
Step-by-step explanation:
If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.
Step 1: Rewrite 2nd equation
x = 5y + 3
Step 2: Substitution
2(5y + 3) - 5y = 26
Step 3: Distribute
10y + 6 - 5y = 26
Step 4: Combine like terms
5y + 6 = 26
Step 5: Isolate <em>y</em>
5y = 20
y = 4
Step 6: Find <em>x</em>
x - 5(4) = 3
x - 20 = 3
x = 23
And we have our final answer!
First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.
72/3 = 24
We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.
To solve this problem subtract 20 from one third of the number 72; 24.
24 - 20 = 4
The number that Barbie is thinking of is 4.
