The vectors are linearly independent if and only if k ≠ -11
<h3>How to solve the vector</h3>
In mathematics, the definition of a vector is a quantity that is made up of both magnitude and also have direction. This type of quantity is not one that is considered based on its position. A very good example of such a quantity with magnitude and direction is acceleration.
Vectors are used to represent items such as position, velocity, physical quantities and others in mathematics and in physics.
In this question,
We have 2v - 3w
We have to multiply 2 by the values of v and multiply 3 with the values of w
this would produce
[2,6,8]-[6,6,12]
subtract w from v
= [-4, 0, -4]
We u as -1, 0 and 10+k
It is not possible to -1 = 10 + k
-11 = k
Hence we have to conclude that they are linearly independent if and only if k ≠ -11

Answer:
Step-by-step explanation:
Without an illustration, I can’t know the position of ∠2 to ∠1.
If the angles are adjacent then ∠2 = 180° - ∠1 = 130°.
Otherwise, ∠2 = ∠1 = 50°
Answer:
a=21
b=25/2
c=77/2
Step-by-step explanation:
from eq 1
a+4=2b => a=2b-4
substituting value of a in eq 2
c-5=a+b => c-5=2b-4+b => c =3b+1
now, substituting value of a and c in eq 3
a+b+c=72 => 2b-4+b+3b+1 =72 => 6b-3=72 => b= 75/6 => b=25/2
substituting value of b in :
c=3b+1 ( you will get c )
then substitute value of b in :
a=2b-4 ( to get a)
Answer:
$3 per lawn
Step-by-step explanation:
one point is (5,15) if you look and divide another would be (1,3) so the rate of price would be $3 per lawn
