Zero slope line coinciding with x axis and undefined slope line coinciding with y axis
There were 15 questions on the science test.
9 divided by 15 is .60%
Answer:
1. x + 4 = 9
Hint: the word 'sum' generally refers to addition.
2. 10<em>a</em> = 70
3. = 15
4. - 4 = 4
Answer:
5 in.
Step-by-step explanation:
radius² = 4² + 3²
radius² = 25
radius = 5
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.
