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

F(x)=3x+10x and g(x)=2x-4, find (f+g)(x)
djyliett [7]

Answer:

15x - 4

Step-by-step explanation:

Add both of the equations together.

f(x) + g(x)

(3x + 10x) + (2x -4)

Then, combine like terms

3x + 2x + 10x = 15x

15x - 4

Jake is choosing between 2 cell phone plans. Plan A costs $15 per month plus $0.08 per minute. Plan B costs $35 per month for un
Alex73 [517]

Answer:

The system of equations is

y=0.08x+16

y=35

Step-by-step explanation:

Let

x ----> the number of minutes of calling time

y ----> the monthly cost of the calling plan

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

In this problem

Plan A

m=0.08\\b=16

substitute

y=0.08x+16 ----> equation A

Plan B

m=0\\b=35

substitute

y=35 ----> equation B

therefore

The system of equations is

y=0.08x+16

y=35

Find an equation of a line through √3,1 / 2) parallel to the line:
vagabundo [1.1K]

Answer:

(a) x=\sqrt{3}

(b) y=\frac{1}{2}

(c) Answer of part a is equation of line x=\sqrt{3} which is parallel to y axis and in part by equation of line is y=\frac{1}{2} which is parallel to x axis

Step-by-step explanation:

We have given points are (\sqrt{3},\frac{1}{2})

(a) Equation of line is given x = -9

We have to find the equation of line parallel to x= -9 and passing through (\sqrt{3},\frac{1}{2})

x = -9 line is parallel to y axis and so slope will be infinite

Equation of line is given by y-y_1=m(x-x_1)

So y-\frac{1}{2}=\frac{1}{0}(x-\sqrt{3})

x=\sqrt{3}

(b) Equation of line is given y=-\sqrt{7}

This line is parallel to x axis so slope will be zero

So equation of line will be y-\frac{1}{2}=0(x-\sqrt{3})

y=\frac{1}{2}

(c) Answer of part a is equation of line x=\sqrt{3} which is parallel to y axis and in part by equation of line is y=\frac{1}{2} which is parallel to x axis
