Answer:
Step-by-step explanation:
n - 10 > 6 <em>add 10 to both sides</em>
n - 10 + 10 > 6 + 10
n > 16
Answer:
y=×+13
Step-by-step explanation:
standard form is any linear equation in y=mx+b
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 2, 3) and r = 3 , then
(x + 2)² + (y - 3)² = 9 ← expand left side using FOIL
x² + 4x + 4 + y² - 6y + 9 = 9 ( subtract 9 from both sides )
x² + y² + 4x - 6y + 4 = 0 → A
its A because 3 plus 6 is 9 and they're both negitive. you then leave the 3x^2 and leave the x/2 both still posivive
