7.
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
and
(x^m)/(x^n)=x^(m-n)
=
9.
2 to 3
4(x-1)=15
to
4x-1=15
the distribuutive prperty
a(b-c)=ab-ac
what he did was
a(b-c)=ab-c
he did not distribute the 4 to the -1
4(x-1)+3=18
minus 3
4(x-1)=15
distribute 4 to x and -1
4x-4=15
add 4 to both sides
4x=19
divide by 4
x=19/4

Since you're going towards the left you can say that your answer is getting "more" negative for the first coordinate. As such you want your answer to be less negative than -21, also the second coordinate seems to be getting "less negative" as such anything less than -9 should not be an option. Lastly the difference between the two points for the first coordinates is 5, more specifically you are subtracting 5 to the first coordinate and for the second coordinate you are adding 3. Following this patter we say that the answer is
and so, the answer is B (-26,-5)
