Answer:
( x+1)^2 + (y+2)^2 = 25
The center is (-1, -2) and the radius is 5
Step-by-step explanation:
x^2 + 2x + y^2 + 4y = 20
Complete the square
2/2 =1 1^2 =1 so add 1 for x 4/2 =2 2^2 = 4 so add 4 for y
x^2 +2x +1 +y^2 +4y+4 = 20 +1 +4
( x+1)^2 + (y+2)^2 = 25
(x+1) ^2 + (y+2)^2 = 5^2
(x - -1) ^2 + (y - -2)^2 = 5^2
This is in (x-h)^2 + (y-k)^2 = r^2 form where (h,k) is the center and r is the radius
The center is (-1, -2) and the radius is 5
Answer:
F) y=3x+13
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=3(x-(-5))
y+2=3(x+5)
y=3x+15-2
y=3x+13
Complete question:
what is the answer to 22 +10x = 0
Answer:
the value of x is -2.2
Step-by-step explanation:
Given;
22 +10x = 0
collect like terms
10x = 0 - 22
10x = -22
divide both sides by 10
Therefore, the value of x is -2.2
