How long will it take an emperor penguin to swim 32 miles if it is swimming 8 mph? A.
4 hours
B.
6 hours
C.
3 hours
D.
12 hours

A: 4 hours

Step-by-step explanation:

Its easier then it may look!

32 m(iles) diveded by 8mph (miles per hour)

= 4 h(ours)

Let me know if its correct or not!^^

If not, I'm sorry!

-1, -2, -3, -4, -6

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
