Answer:
Step-by-step explanation:
distance = square root [
+
]
where you have two points on the line
Point 1 = P1 = (x1,y1)
point 2 = P1 =(x2,y2)
Answer:
(x - 6)^2 + (y + 4)^2 = 4
Step-by-step explanation:
formula for a circle
( x - h )^2 + ( y - k )^2 = r^2
(h,k) is the center
r is the radius
(6,-4) is center
2 is radius
Substitute in numbers and watch the negatives.
Answer:
x = ± 15
Step-by-step explanation:
Given
x² = 225 ( take the square root of both sides )
x = ±
= ± 15
That is x = - 15 0r x = 15
