Module Six Project Option 1
Instructions
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.
Part 2: Writing Equivalent Expressions
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Use either the commutative property or combine like terms to create an equivalent expression.
Use the distributive property to create an equivalent expression.
Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?

Step-by-step explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=3, y1=2, x2=0, y2=−1.
Plug the given values into the formula for slope: m=(−1)−(2)(0)−(3)=−3−3=1.
Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).
b=2−(1)⋅(3)=−1.
Finally, the equation of the line can be written in the form y=mx+b.
y=x−1.
Answer:
The slope of the line is m=1.
The equation of the line in the slope-intercept form is y=x−1.
The equation of the line in the point-slope form is y−2=1(x−3).
The equation of the line in the point-slope form is y+1=1x.
The general equation of the line is x−y−1=0.

Step-by-step explanation:
A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.75 mi long. You walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk? Round your answer to the nearest hundredth. Use 3.14 for π.
Answers
C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.
You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer

What is the Volume of the box 385 cubes?
Answers
Answer:You can calculate the volume of a box by multiplying length x width x height. Using the example of the single wall box this will be 102 x 102 x 102 which equals 1,061,208 cubic millimeters (㎣).
Step-by-step explanation:
The Volume of the box is 385/27 inch³.
What is Volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.
Length = 11/3 inch
width - 5/3 inch
Height = 7/3 inch
So, the Volume of cuboidal box
= l w h
= 11/3 x 5/3 x 7/3
= 385/ 27 inch³
Also, Number of small cube = Volume of box/ Volume of small cube
385 = Volume of box / (1/27)
Volume of box = 385/ 27 inch³

Mr. Paulsen challenges Olivia and Angelica to move figure ABCDE onto figure A"B"C"D"E" using a series of two different transformations. They give two different answers.
Answer the questions to investigate ways to transform ABCDE.
1. Olivia finds a combination of two different transformations that moves ABCDE onto A"B"C"D"E". What is one way she might have done this?
2. Angelica reflects ABCDE over the y-axis and translates it up 8 units. Does her transformed figure match A"B"C"D"E"? If not, describe how her transformed figure compares to A"B"C"D"E".
3. Michael says he can move ABCDE onto A"B"C"D"E" with one transformation by translating ABCDE diagonally so that it moves 8 units up and 10 units right. Is he correct? Explain why or why not.
Answers
Problem 1
One method Olivia could have used is to reflect over the x axis and then translate 10 units to the right.
Let's apply these set of steps to point C.
C = (-2,-4)
C' = (-2,4) after reflecting over the x axis; y coordinate flips in sign
C'' = (8,4) after shifting to the right 10 units; add 10 to the x coordinate
Point C(-2,-4) moves to C''(8,4) which is shown in the diagram. I'll let you check the other four points.
-----------
Another method Olivia could have used is to shift to the right 10 units first, then reflect over the x axis. In this case, the order doesn't matter. Though for some other combinations of transformations, order does matter.
============================================================
Problem 2
Reflecting over the y axis will have the point (x,y) turn into (-x,y). Only the x coordinate changes, and we flip the sign here. The y coordinate stays the same.
A point like C(-2,-4) becomes C'(2,-4) after the y axis reflection. Shifting up 8 units means we add 8 to the y coordinate to arrive at C''(2,4) but this does not match what the diagram shows. Therefore, Angelica's method is incorrect.
You should find other inconsistencies for the other four points as well.
============================================================
Problem 3
Michael's method isn't correct either. He does not apply an x axis reflection and instead relies entirely on translations to move ABCDE to A''B''C''D''E''
At a quick glance, it looks like Michael may be correct. But upon a much closer look, you'll see that things don't line up perfectly.
Instead of point C, we'll pick on point D this time.
D is located at (-6,-2). If we shift up 8 units, then we add 8 to the y coordinate to get to D'(-6,6). Then add 10 to the x coordinate to shift 10 units to the right. This leads us to D''(4,6).
However, the diagram shows D'' is actually at (4,2)
I'll let you check the other points. You should find that only points C and E go to the correct locations, but the other points do not. Again, this is because Michael did not apply an x axis reflection. His figure of A''B''C''D''E'' is upside down compared to what it should be.
============================================================
To summarize, the methods described in problem 1 are the correct way to get ABCDE to move to A''B''C''D''E''. If Olivia followed either of those two methods, then she is correct. Both Angelica and Michael have incorrect methods.

Which of the following numbers is not part of the solution x ≤ -2
A. -2.45
B. -2
C. -8
D. -1.76
Answers
Answer:
D.
Step-by-step explanation:
In order for it to be the solution, it must be less than or equal to -2. D (-1.76) is bigger than -2, which means it is not a part of the solution.
Answer:
D
Step-by-step explanation:
First of all, let's try all of the options available.
We know that x must be LESS THAN or EQUAL to -2
So, let's get on with it!
Option A:
Is -2.45 LESS THAN or EQUAL to -2?
Well, according to the number line, if the number is left of the number that you are comparing, -2 then it is less than.
So this option is alright.
Option B:
-2 is not LESS THAN but ONLY EQUAL to -2.
So this option I THINK is alright, but am not sure. But I think it is alright because if it is less than and equal to, then that means it ALSO INCLUDES -2.
Option C:
Again, -8 is located to the LEFT side of -2, which means -8 IS LESS THAN or Equal to -2.
So this option is alright.
Option D:
-1.76 is to the RIGHT side of -2, which means it is GREATER than -2.
So this option is CUT OFF
Hope this helps.
