Alub of water is emptied at a rate of 3 gallons per minute. The equation y-12 = -3(x - 1) models the amount of water
remaining where x is time (in minutes) and y is the amount of water left in gallons). Analyze the work shown below
to determine the initial amount of water.
Salve for the variable
9-12= 3tr - 1)
9-12= 3x+3
y=-
3 15
2. Write the equation using function notation.
=3x+15
The tub started with

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
