There are 8 more dairy cattle on the farm than beef cattle.
Answer:

Step-by-step explanation:
In 2002, a robot explored a tunnel 210 feet long inside the
Great Pyramid in Egypt. The robot could travel about 10 feet per
minute.
The speed of the robot is 10 feet per minute
we need to find the equation for giving distance y
the robot travel in x minutes
to time is x minutes
Distance = speed x time
speed=10, distance is y and time is x

The first problem:y = -2 x² ⇒⇒⇒ x² = -y/2 →(1)33 x² + y² = 27 → (2)
By substitution from (1) at (2) with the value of x²
∴ 33 (-y/2) + y² = 27
∴ y² - 16.5 y - 27 = 0
a = 1 , b = -16.5 , c = -27
∴

∴ y = 18 or y = -3/2
By substitution from at (1) with the value of y
for y = 18 ⇒⇒⇒ x² = -18/2 = -9 (unacceptable)
for y = -3/2 ⇒⇒⇒ x² = -(-3/2)/2 = 3/4
∴

The correct options are 2 , 7
Solution of the system of equations is

and

==================================
The second problem:
The general equation of the hyperbole is

For the given equation:

a² = 225 ⇒⇒⇒ a = √225 = 15
b² = 36 ⇒⇒⇒ b = √36 = 6
∴ the slope of the <span><span>asymptotes = </span>b/a and -b/a

</span><span>-b/a = -6/15 = -2/5
</span><span>
</span><span>∴ m = 2/5 and m = -2/5
