Aleak in a pool causes the height of the water to decrease by 0.25 feet before the leak is fixed. after the leak is fixed, the height of the water is 4.75 feet. the equation -4.75 = x + (-0.25) can be used to find x, the original height of the water in a pool. what was the original height of the water in the pool?

-4.75 = x + (-0.25)  well x=5

and the 4.75 is positive

5 feet

Step-by-step explanation:

Since the height of the water is 4.75 feet, the equation is

4.75 = x + (-0.25)

To solve, add 0.25 to each side:

4.75+0.25 = x+(-0.25)+0.25

5.00 = x

its 4 because 2 times 2 is 4, if you double the number two you get four

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
