Arobber drove out of town at 5am at 60mph. the policeman went in pursuit of him at 7am, traveling at 70mph. what time was it when the policeman got within 10 miles of the robber?

12/11c

or

12

c

11

there is no grid

step-by-step explanation:

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)

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
