The measure of an arc refers to the arc length divided by the radius of the circle. The arc measure equals the corresponding central angle measure, in radians. That's why radians are natural: a central angle of one radian will span an arc exactly one radius long.
Answer:
for which question???????????????
Answer: x = -1 and y = 9
The two equations are:
-9x + 2y = 23
-4x -y = -3
Now find for x in the first equation...
-9x + 2y = 23
-9x = 23 - 2y
x = (23 - 2y)/-9
Now place this value of x in the second equation and find for y...
-4{(23-2y)/-9} - y = -3
-92 + 8y + 9y = -3 * -9
17y = 27 + 92
y = 119/17
y = 7
Now place the value of y in the first equation," -9x + 2y = 23 " and find x
-9x + 2*7 = 23
-9x + 14 = 23
-9x = 23-14
x = 9/-9
x = -1
There you go! Hope it helps

Ans:8x-3y=27
Step-by-step explanation:
let,A,B be the line which have points (3,-1),(6,7)
here,
(3,-1)=(x1,y1)
(6,7)=(x2,y2)
then,
slope of line AB =(y2-y1/x2-x1)
=(7+1/6-3)
=8/3
Now,
equation of the line AB,
(y-y1)=m(x-x1)
(y+1)=8/3(x-3)
3y+3=8x-24
-8x+3y=-24-3
-8x+3y=-27
-(8x-3y=27)
8x-3y=27
Hence, the equation of the line through the points (3,-1) ,(6,7) is 8x-3y=27.
True, it would be equilateral
