Answer:
A
Step-by-step explanation:


Remember that
x^(b-c)
Using that
=3^(1/2x-1/2)=3^((x-1)/2)

So we can say:
, because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
The distance of A from the origin.
√(5²+3²+(-2)²)= √(25+9+4)
=√38
=6.2
The distance of B from the origin
√(2²+(-4)²+8²=√(4+16+64)
=√84
= 9.2
Answer:
k = 4
Step-by-step explanation:
Hello!
3k + 16 = 8 + 5k
Subtract 3k from both sides
16 = 8 + 2k
Subtract 8 from both sides
8 = 2k
Divide both sides by 2
4 = k
The answer is 4
