Answer:
4 1/4
Step-by-step explanation:
1/2 + 1/2 + 2= 3
3 + 1 + 1/4= 4 1/4
Answer:
The answer to your question is (x - 7)² + y² = 81
Step-by-step explanation:
Data
Center = (7, 0)
radius = 9
Process
To find the standard equation of a circle, just substitute the values of the center and the radius.
Standar equation of a circle
(x - h)² + (y - k)² = r²
-Identify the values of h and k
h = 7 k = 0 and r = 9
-Substitution
(x - 7)² + (y - 0)² = 9²
-Simplification
(x - 7)² + y² = 81

Answer:
thanks for the points
Step-by-step explanation:
Solution
Find the y-intercept for following equation:
![f(x)=-(x+1)^2](https://tex.z-dn.net/?f=f%28x%29%3D-%28x%2B1%29%5E2)
Using the slope equation formular:
![\begin{gathered} y=mx+c \\ f(x)=-(x+1)^2 \\ f(x)=-x^2-2x-1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%3Dmx%2Bc%20%5C%5C%20f%28x%29%3D-%28x%2B1%29%5E2%20%5C%5C%20f%28x%29%3D-x%5E2-2x-1%20%5Cend%7Bgathered%7D)
The value of y when x = 0
![\begin{gathered} f(0)=-0^2-2(0)-1 \\ y=-1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%280%29%3D-0%5E2-2%280%29-1%20%5C%5C%20y%3D-1%20%5Cend%7Bgathered%7D)
Hence the answer is - 1
