Paul is scuba diving and is 3.5 feet below sea level he is descending at a rate of 0.5 feet per minute if paul is now at 12 feet below sea level how many minutes has he been diving ?

x= 149. 24+7=31. 180-31=149

your welcome

$12. that is my answer.

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)
