Answer:
x^2+2x+y^2−2y−7=0
Step-by-step explanation:
The method from converting to standard to general is very simple
this equation in standard form would be
(x+1)^2+(y-1)^2=9
This is because whatever the center of the circle is, you take the negative/positive version of that number
The center is at -1, 1. So it would flip to be put into the equation as 1, -1.
9 is the radius^2.
The radius is 3.
To convert to general form you just simplify
x^2+1+2x = (x+1)^2
y^2 + 1 -2y = (y-1)^2
x^2 - 2x + y^2 - 2y + 2 = 9
get the nine on the left side
x^2 -2x +y^2 - 2y 2 - 9 = 0
x^2+2x+y^2−2y−7=0
Give brainliest, please!
Hope this helps :)
Answer:
Augusto was biased and only asked his friends
Step-by-step explanation:
Augusto should've asked 20 random people, since the people he hangs around the most probably have the same habits
This was not a fair collection of data
126.56 feet
This can be found by finding the vertex of the parabola. You can find the t value using -b/2a and then plug that in to find the h value.
Answer:
15.75 x¹⁰y¹⁹
Step-by-step explanation:
Fifth term is at r = 4
9C4 × (-y/4)⁴ × (2x²y³)⁵
126 × y⁴/256 × 32x¹⁰y¹⁵
(63/4) x¹⁰y¹⁹
15.75 x¹⁰y¹⁹
