Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.
Answer:
6x^2+5x-6
Step-by-step explanation: The only change you have to is add -3 and 8 which is 5 (Dont forget the x) and there you have it .
Answer:
Step-by-step explanation:
*The dashes are the fraction line*
To find slope...
difference between y
-------------------------------
difference between x
2 - k
------- = 5
3 - 4
3-4 = -1 so...
-1 ( 2 - k ) = 5
k - 2 = 5
k = 7
