The equation d = 3t represents the relationship between the distance (d) in inches that a snail is from a certain rock and the time (t) in minutes. a. How many minutes does it take the snail to get 9 inches from the rock? b. How far will the snail be from the rock after 9 minutes?

A. It will take 3 minutes for the snail to travel 9 inches

B. It will travel 27 inches in 9 minutes

Step-by-step explanation:

We can do the first part by replacing d with 9. This is because we are looking for how long it will take to reach a certain distance.

9=3t

t=3

It will take 3 minutes for the snail to travel 9 inches

Next step, we replace t with 9 because we are looking for how much distance it will cover over a certain amount of time

d=3(9)

d=27

It will travel 27 inches in 9 minutes

a. How many minutes does it take the snail to get 9 inches from the rock?

d = 3t

t = d/3

t = (9) / 3

t = 3

It takes 3 minutes the snail takes the snail to get 9 inches from the rock.

b. How far will the snail be from the rock after 9 minutes?

d = 3(9)

d = 27

27 inches far.

answer:

your answer is: c. 196 7/8 in^3.

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)
