Answer:
Step-by-step explanation:
Use the formula 0 = b^2-4ac
0 = -b^2-4(2)(-9)
0 = -b^2+72
b^2 = 72
b = square root of 72
b = 2 real numbers
<span>M divides JK into two parts with lengths in a ratio of 1:3
so JM:MK is either 3:1 or 1:3
before solving for M, need to find mid-pt of JK, point L
L is at (-4+8)/2 and (11-1)/2 so L is at (2,5)
mid-pt of JL is at (-4+2)/2 and (11+5)/2 so it is at (-1,8)
and mid-pt of LK is at (8+2)/2 and (-1+5)/2 so it is at (5,2)
note that these pts are the fourths. They </span><span>divide the segment into fourths, so the three-quarter segment is indeed thrice as long as the quarter segment. They are the ans for pt M.
M is (-1,8) or (5,2)
