Answer:
line B.)
Step-by-step explanation:
2x+5y=10
5y=-2x+20
(5y/5) (2x+10/5)
y= (-2/5)x +2
Answer:
The central angle is within the range π to 3π/2
Step-by-step explanation:
To convert from degrees to radians, we multiply the angle in degrees by 180/π.
To convert from radians to degree, we multiply the angle in radians by 180°/π.
π/2 = π/2 X 180°/π= 90°
π rad = π X 180°/π= 180°
3π/2 = 3π/2 X 180°/π= 270°
2π = 2π X 180°/π= 360°
Therefore the angle 250 which is between 180 and 270 is within the range :
π to 3π/2
(5/6)/ (-2/3)
5/6 x (-3/2)
-15/12
-5/4 is your answer
hope this helps
