1. A large tank has 9 gallons of water in it. Water begins flowing into the tank. (5 points) a. Define a variable that represents how much water is added to the tank. Use precision when defining your variable. (1 point) b. Use your variable to write an expression that represents the number of gallons in the tank. (2 points) c. Explain how your expression connects to the given scenario. (What do your numbers represent? Why did you use an operation like addition, subtraction, multiplication or division in your expression?) (2 points)

one that is bigger than 3 1/2

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

6e14 is the answer.

too hard the other guy did it
