1) 7.4 + (-3.9) = y
2) z = -13.9 + (-12.5)
3) k = -3.91 - (-0.6)
4) a = -34.1 + (-17.63)
5) y = -18.12 - (-7.3)

It may seem like the black one at first, but rough absorbs more sunlight than smooth, and black more than white.

Find a necessary condition for the three planes given below to have a line of intersection.

-x +ay+bz=0
ax-y+cz=0
bx+cy-z=0




in order to get a line of intersection between the planes..i know i need one line of the matrix to be [0 0 0|0]




well heres the attempt..and its wrong

[ -1 a b | 0
a -1 c | 0
b c -1| 0 ]

=>

[-1 a b | 0
0 (a^2-1) ba+c | 0 (aRow1 + Row2)
0 (ab+c) b^2+1 | 0 ] (brow1 + Row 2)


=>

[ -1 a b | 0
0 a^2 -1 ba+c |0
0 0 2abc +c^2 - a^2 + b^2 +1) |0 ] (ab+c row2- a^2-1 Row1)


then what i did ..by inspection i made 2abc+c^2 -a^2 +b^2 +1 = 0 by letting a=b=1, and c=-1......

but that doesnt work becasue that owuld make plane 1 and 2 the same plane.

i need help

thanks
