You have a bottle of water with a leak. after 2 seconds there is 28 ounces left in the bottle. after 6 seconds there are 20 ounces left in the bottle. how much water was in the bottle initially

32 ounces.

Step-by-step explanation:

We can think of this as a linear equation.

y = a*x + b

where y is the amount of water in the bottle, a is the rate at which loses water, x is the number of seconds and b is the initial amount of water.

We have two pairs:

2 seconds - 28 ounces left or (2, 28)

6 seconds - 20 ounces left or (6, 20)

Now we can write the value of a as:

a = (20 - 28)/( 6 - 2) = -8/4 = -2 ounces per second.

Then our function is:

y = -2x + b

and we know that when x = 2, y = 28, so we have:

28 = -2*2 + b = -4 + b

b = 28 + 4 = 32

the initial amount of water in the bottle is 32 ounces.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
