The standard equation of a circle:
(y-k)² + (x-h)² = R² (1), where R is the radius and h, k are the coordinates of the center.: C(h, k)
In the problem the coordinates of the center C(2,-1).
Replace in (1) h by 2 and k by -1:
(y+1)² + (x-2)² = 25
Y^2-9y+81 can not be factored with any rational numbers
3/4 = 21/28 after multiplying top and bottom of 3/4 by the value 7
3*7 = 21 and 4*7 = 28
The goal is to get 3/4 into an equivalent fraction that has 28 as the denominator.
------------------------------------
So 3/4 - 1/28 is the same as 21/28 - 1/28
The denominators are the same. We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28
We have
21/28 - 1/28 = (21-1)/28 = 20/28
Now reduce 20/28 as much as possible. Divide both parts by the GCF 4
20/4 = 5
28/4 = 7
The final answer is 5/7
Answer:
-14
Step-by-step explanation: 12+(-26)= -14
You add 12 into -26 and get -14. OR you can subtract -26 by 12 and still get the same answer but adding is faster and easier.
