The image shows the linear graph for a family that hired a babysitter for a day. The family gave the babysitter some money up front to buy herself some lunch, and then paid her a constant hourly rate for the hours she worked. Click the thumbnail image to see the full size image.
Which 2 of the following statements are TRUE about the SLOPE of this line? Select the TWO statements that are accurate.
A. The slope is 10
B. The slope is 1/10.
C. The slope tells me that the hourly rate for babysitting is $10.
D. The slope tells me that the hourly rate for babysitting is $20.
Answer:
A and c
Step-by-step explanation: i did some research.
The slope of a function is the rate of change of the function.
The true statements are:
A. The slope is 10 C. The slope tells me that the hourly rate for babysitting is $10.From the graph, we have the following points
[tex]\mathbf{(x_1,y_1) = (0,10)}[/tex]
[tex]\mathbf{(x_2,y_2) = (1,20)}[/tex]
The slope (m) is calculated as follows:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{20-10}{1-0}}[/tex]
[tex]\mathbf{m = \frac{10}{1}}[/tex]
[tex]\mathbf{m = 10}[/tex]
The slope is the rate of change of the y values over the x values.
Hence, the true statements are:
A. The slope is 10 C. The slope tells me that the hourly rate for babysitting is $10.Read more about slopes at:

Now that you’ve identified several points on the graph, it’s time to create the graph this spreadsheet. Plot the time (in hours) along the x-axis, and the distance (in miles) along the y-axis. Follow these steps to create the graph:
Open a new worksheet in the spreadsheet.
In cells A1 through A7, enter the number of hours for each data point. Be sure to start with 0. The order of your data points is important.
In cells B1 through B7, enter the number of miles for each data point. Be sure to start with 0. Again, the order of your data points is important.
Click and drag to highlight cells A1 through A7 and B1 through B7 into which you entered data values in steps 2 and 3.
From the main menu, click Insert. In the drop-down menu for charts, select Scatter with Straight Lines and Markers.

-24x = -3 what is the solution to the equation?
Answer:x = 1/8 = 0.125
Step-by-step explanation:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-24*x-(-3)=0
Pull out like factors :
-24x + 3 = -3 • (8x - 1)
Solve : -3 = 0
Solve : 8x-1 = 0
Add 1 to both sides of the equation :
8x = 1
Divide both sides of the equation by 8:
x = 1/8 = 0.125
Answer:
1/8 = 0.125

Ok so this question baffles me lol does anyone know how I would even start doing this!?
Answer:
The expression is 106.9 /4 = p or 4p =106.9
To solve:
106.9 /4 = 26.72 approx.*
So each person will most likely pay $26.72.

You are creating your own real-world problem or word problem using Pythagorean Theorem. You create the problem and solve it. Use what you find to help you create your own problem. It does not have to be a really hard problem.
Answer:
A man's garden keeps getting attacked by rabbits, so he decides to put a fence around it. the garden is in the shape of a right triangle. The people who build the fence measure side a and b, side a has a length of 6 yards. Side b has a length of 8 yards. What is the total length (in yards) of fence the builders will need?
The pythag equation is:
a^2+b^2 =c^2
So, we plug in 6 for a and 8 for b and we get:
(6*6)+(8*8)=c*c
36+64=c*c
100=c*c
Now, we all know that 10*10 is 100 so:
c=10
Now we add 10 to 8 and 6 and we get:
24
The builders will need 24 yards of fence.
Solve the problems from 10to 12

The sets of numbers 6, 8, 10 and 5, 12, 13 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!
Answer:
We know that the Pythagorean Theorem is a² + b² = c². First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.
Hope this helps :-)
