Answer:
No
Step-by-step explanation:
3x - 6 = 12
3x = 18
x = 6
The only solution of the equation 3x - 6 = 12 is x = 6.
Answer: No
Answer:
7/4
Step-by-step explanation:
Answer:
Therefore the given vectors are orthogonal for b = 0,±3.
Step-by-step explanation:
If
and
are two vectors orthogonal, then the dot product of
and
will be zero.
i.e 
If
and 


Given two vectors are (-18,b,9) and (b,b²,b)
Let

and

Therefore,


=(-18).b+b.b²+9.b
= -18b+b³+9b
= b³-9b
Since
and
are orthogonal. Then
= 0.
Therefore,
b³-9b= 0
⇒b(b²-9)=0
⇒b =0 or b²=9
⇒b=0 or b =±3
Therefore the given vectors are orthogonal for b = 0,±3.
