Answer:
4). (x + 2)^2 + (y - 1)^2 = 25.
Step-by-step explanation:
x^2 + y^2 + 4x - 2y - 20 = 0
x^2 + 4x + y^2 - 2y = 20
Completing the square on the x and y terms:
(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20
(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1
(x + 2)^2 + (y - 1)^2 = 25.
Answer:
the answer is B
Step-by-step explanation:
hoped I helped:)
Answer : B
x^2-9x+14
Lets factor 
We find out two factors whose product is +14 and sum is -9
Two factors are -2 and -7, we split the middle term -9x using -2 and -7
Group first two terms and last two terms
Then factor out GCF from each term
so x-2 is one of the factor
0 = 2 - 3y + 12x
0 = 12x - 3y + 2
3y = 12x + 2
3 3
y = 4x + ²/₃
Change the problem into an equation in slope-intercept form.
What is it you need? If it's the equation: P=.75+7.95.
