3-(4-4)+4 is what ? i confused about if when u do the 4-4 that zero then what do you do next?

Subtract

New Problem:

Remove 0

Before:

After:

Add

Note: You remove 0 because your just subtracting 3-0 which is still 3. Therefore you can just remove 0 and forget about it. After you remove 0 you can just add 3+4.

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

graph of this function as shown below:

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
