x₁ + x₂ y₁ + y₂
 2 = M 2 = M

x + 8 y + -2
 2 = -4 2 =6
multiply both sides by 2.

x+8=-8 y - 2 = 12
x = -16 y = 14

Final Answer: (-16, 14)

Answer:

The correct option is: 32.4 km/h

Step-by-step explanation:

The fastest recorded speed of a turtle while swimming is 9 m/s.

Now, 9 m/s $=\frac{(9)meters}{(1)second}$

1 kilometer= 1000 meter

So, 1 meter $= \frac{1}{1000}=0.001$ kilometer

and 9 meters $=(9*0.001)kilometer = 0.009$ kilometer

Now, 1 hour = 3600 seconds

So, 1 second $=\frac{1}{3600}hour$

Thus, we will get.........

$\frac{(9)meters}{(1)second}=(\frac{0.009}{\frac{1}{3600}}) kilometer/hour =(0.009*3600)=32.4 km/h$

So, the speed of the turtle will be 32.4 km/h.
