Answer:

Step-by-step explanation:

The graph is a plot of distance in kilometers on the vertical axis against time, in hours on the horizontal axis.

1) The x-intercept is the point on the horizontal axis at which y = 0. This means that at this point, the distance from the beach to her house is zero. From the graph, the point is 6 hours.

2) The y-intercept is the point on the vertical axis at which x = 0. This means that this point is the point at which she started to ride. At this point,time = 0 hours and the distance from the beach to her house is 75 kilometers.

3) slope is expressed as

Change in y / change in x

We will pick 2 points on the y axis and two corresponding points on the x axis.

Change in y = y2 - y1

Change in x = x2 - x1

Slope = (0-75) / (6 - 0) = -75/6

Slope = - 12.5 kilometers per hour

The slope represents the rate at which her distance from the beach changes with time. It represents her velocity. It is negative because her distance from the beach is decreasing with time

Answer:

1. Distance from Katie's House to the beach = 75 km

2. Hours that it takes to get to the beach = 6 hrs

3. -12.5 which tells us the rate at which katie traveled which was 12.5 km per hour

Steps to 3.

Rise/Run = -75/6 = -12.5 = slope

What is the equation of the inverse function A(n)=3n-20
Allisa [31]

Answer:

A^{-1}(n)=\frac{1}{3}n+\frac{20}{3}

Step-by-step explanation:

First, let's change those variables to x and y, just for the sake of convenience.  In order to find the inverse of a function algebraically, switch the x and y coordinates, then solve for the new y.  Letting y = A(n) and x = n (we will switch them back when we're done):

y = 3x - 20.  This is linear; a line with a slope of 3 and a y-intercept of -20.  When we switch the x and the y, we get:

x = 3y - 20.  Now we solve for the new y.  Begin by adding 20 to both sides:

x + 20 = 3y.  Now divide both sides by 3:

\frac{x+20}{3}=y, or to write it in slope-intercept form, like the function you started with:

y=\frac{1}{3}x+\frac{20}{3}

This is also a line, with a slope of 1/3 and a y-intercept of +20/3

Now, replacing:

A^{-1}(n)=\frac{1}{3}n+\frac{20}{3}

That is how to write the inverse using function notation.  The little -1 as an exponent tells us that this is the inverse of the function A(n).
