A Delta airplane is at 10 1/2 miles. If the plane drops 2 1/4 miles in altitude, what is the new altitude?

8 1/4

Step-by-step explanation:

10 2/4 - 2 1/4= 8 1/4 . you have to find what 1/2 is in 10 1/2 which turns into 2/4 and then you do 10 2/4 - 2 1/4 and you subtract because it dropped in altitude which ends up with 8 1/4 miles

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
