My turtle tank requires at least 2 grams of conditioning salt per liter. i test the water and notice it has approximately 1 g/l and the tank is about 100 liters. i make a very concentration salt solution with concentration 10 g/l of conditioning salt and start pouring a cup in the tank and remove a cup of well-mixed solution out. the rate of adding and removing solution is about 5 l/min. after how many full minutes will the solution have the correct concentration of conditioning salt.

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)

according to egenuity the answer is
