Will give the brainiest and 20 ! the speed of a ship is given by , where d is the distance the ship travels in 3 hours. if the ship travels 48 miles in 3 hours, what is the speed of the ship?
a.12 miles per hour
b.16 miles per hour
c.45 miles per hour
d.51 miles per hour

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

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)
