11: 6(3x+4y)
13a: 5x(3-4y)
13b: they but “x” next to 4 when the expression didn’t have the “x^2” anywhere
14a: find the common factors of each number
Let me see if I can work this out real quick
Answer:
The center is at (-3, -2) and the radius = 1.
Step-by-step explanation:
We can do this by converting the given equation to standard form.
x^2+6x+y^2+4y+12=0
x^2+6x+y^2+4y = -12
Completing the square on the x and y terms:
(x + 3)^2 - 9 + (y + 2)^2 - 4 = -12
(x + 3)^2 + ( y + 2)^2 = -12 + 9 + 4
(x + 3)^2 + ( y + 2)^2 = 1
So the center is (-3, -2) and the radius = 1.
You can't solve for x. Y=mx+b is slope intercept form and is used to graph equations
