X=-1/9 I used a calculator
if there's eight students on the minibus then there's 4 boys and 4 girls on the minibus
Answer:

Find where the expression
5
x
x
+
6
is undefined.
x
=
−
6
Consider the rational function
R
(
x
)
=
a
x
n
b
x
m
where
n
is the degree of the numerator and
m
is the degree of the denominator.
1. If
n
<
m
, then the x-axis,
y
=
0
, is the horizontal asymptote.
2. If
n
=
m
, then the horizontal asymptote is the line
y
=
a
b
.
3. If
n
>
m
, then there is no horizontal asymptote (there is an oblique asymptote).
Find
n
and
m
.
n
=
1
m
=
1
Since
n
=
m
, the horizontal asymptote is the line
y
=
a
b
where
a
=
5
and
b
=
1
.
y
=
5
There is no oblique asymptote because the degree of the numerator is less than or equal to the degree of the denominator.
No Oblique Asymptotes
This is the set of all asymptotes.
Vertical Asymptotes:
x
=
−
6
Horizontal Asymptotes:
y
=
5
No Oblique Asymptotes

Here you can use proportion:
The ratio betwen €1.2 to £1
is the same as the ratio between €180 to £x
Mathematically this means that
.
Now
Answer: €180 is £150
