Answer:
Step-by-step explanation:
hello : 14x + 13y = -8
19x + 14y = 11
test : put x=5 and y=6
14(5)+13(6)≠ -8
conclusion : (5 , 6) is not solution

Answer:(x-3)=-(y-5)=z
Step-by-step explanation:
Given
the point through which line passes is (3,5,0)
so we need a vector along the line to get the equation of line
It is given that line is perpendicular to both i+j & j+k
therefore their cross product will give us the vector perpendicular to both
v=(i+j)\times (j+k)=i-j+k
therefore we get direction vector of line so we can write
=t
i.e.
x=t+3,y=-t+5,z=t
Answer:
The number after - 2 is - 3.5.
Step-by-step explanation:
Follow the pattern
Let the number be after -2
as in the question after 4 we have 2.5 then 1 and so on.
if we subtract 4 from 2.5 we get
2.5 - 4 = -1.5
similarly: 1 - 2.5 = -1.5
-0.5 - 1 = -1.5
and now
x -(-2) = - 1.5
x = - 1.5 -2
x = - 3.5
so the number after - 2 is - 3.5.
