A(7, -2) B(-4, 9) C(-3,-1)
AB² = (7 - -4)² + (9 - -2)² = 121 + 121 = 242
AC² = (7 - -3)² + (-2 - -1)² = 100 + 1 = 101
BC² = (-3 - -4)² + (9 - -1)² = 1 + 100 = 101
Since AC² + BC² ≠ AB² this isn't a right triangle
It is clearly an isosceles triangle because AC² = BC²
Answer: Isosceles

Answer:
A.) 12
Step-by-step explanation:
The actual line of best fit places the value of y at about 11.95.
You can guess that the line of best fit will be between the lines of given points, tending toward below center at x=9 and above center at x=2. The answer choices 9, 17, and 1 are thus rendered untenable. The only one that makes any sense is (x, y) ≈ (9, 12).
Isolate the variable y
Line a: 3y = x+6
y = 1/3x + 2
Line b: 3y = x+18
y = 1/3 x + 6
Line c: 3y = 2x+9
y = 2/3x +3
Explanation:
Lines a and b are parallel because they have the same slope of 1/3.
Answer:

Step-by-step explanation:
Given:
Angle of arc = 300°
Radius of circle = 11 miles
Take π as 3.14
Required:
Area of the major sector
Solution:
Area of sector is given as: angle of arc/360*πr²
Thus,
