1. A tank has 25 gallons of chemicals in it. Chemicals were added to the tank at a rate of 7
gallons per second. Which equation models the relationship between t, the number of
gallons of chemicals, and w, the number of seconds chemicals are being added to the
tank?
A. T = 25W + 7
B. T = 32w
C. T = w + 32
D. T= 7w + 25

55? i think maybe

step-by-step explanation:

this doesn't make sense lol

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)
