A correlation coefficient of -1 shows a perfect negative correlation
Answer:Except -1 for all real values of k given the equations has a unique solution.
Step-by-step explanation:
Except -1 for all real values of k given the equations has a unique solution.
Explanation:
Compare given linear pair of equations
(3k+1)x+3y-2 = 0 ----(1)
(k²+1)x+(k-2)y-5=0 ----(2)
with
----(2)
----(3)
we get ,
and
\* Given linear equations have unique solution *\
=> 3k(k-2)+1(k-2)≠3k²+3
=> 3k²-6k+k-2≠3k²+3
=> 3k²-5k-3k²≠3+2
=> -5k ≠ 5
Divide each term by (-5) , we get
=> k ≠-1
Therefore,
Except -1 for all real values of k given the equations has a unique solution.
X= 20
Work:
7 times 2 is 14 so you will
muliltiply 10 by 2 which is 20.
Answer:
Folow these steps:
find the slope:
equation for slope: y2-y1 / x2- x1
4-2 / 4-1
2/3 is the slope
y=mx+b
y=2/3x+b
Now just plug in the x and y of either point into the equation. IM using (1, 2)
2=2/3(1)+b
2=2/3+b
b=1 1/3
Now that we have the y intercept and slope, construct the equation:
y=2/3x+1 1/3
