In order to answer the question we need a picture of some kind
ANSWER

EXPLANATION
Recall that,

That is why

is equivalent to

This implies that,

This is the same as,

When we are dividing by

we move the decimal point backwards two times.
This implies that,
Answer:
the answer is 1/2 which loos like "D"
Step-by-step explanation:
the top ends up being x ^-8 and the denominator is x^-7
which is x^&/x^8 = 1/x = 1/2
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=

Also y=

We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
