Journal #5

Journal Linear Inequalities  Due Friday 12/13

Jim owns a moving company. On a particular job Jim was moving some beds and sofas, and was interested in determining how many beds and/or sofas he could load into a semi-trucks trailer. Jim knows that the trailer can hold at most 80 beds and 44 sofas. Jim also knows that the total volume of the trailer is 4000 cubic feet and that each bed takes up 50 cubic feet and each sofa takes up 90 cubic feet. Write an inequality to represent the following:

a.) How many beds the trailer can hold? Explain what this inequality represents.
b.) How many sofas the trailer can hold? Explain what this inequality represents.
c.) How many sofas and beds can fit in the total cubic feet of the trailer? Explain what this inequality represents.

Solve the system of linear inequalities by graphing. Be sure to indicate where the solution is.

Journal #4 Function Notation

Must be 150 Words, Due Friday 12/6

What is function notation? Why do we use it? What do f(x) and y have in common? Give an example of an equation in function notation and solve for a value. Explain the process.


*Extra Credit 2 points each*
Try to complete i and j on the function notation homework sheet.

Parallel and Perpendicular Lines

Below is the link to a video about parallel and perpendicular lines.  This video covers important information about parallel and perpendicular lines and goes through a few examples.


Remember the slopes of lines that are parallel are the same. The slopes of lines that are perpendicular are opposite reciprocals.

Journal Linear Equations

When writing a linear equation which method do you prefer: Standard form (Ax + By= C), Slope-Intercept Form (y=mx+b), of Point-Slope from (y-y1 = m(x-x1) ). Why? Why do you think we learn different ways to write linear equations?

Due 11/22 Must be 150 words


Extra 5 points (optional)

Find a real life situation involving a linear equation or a real life situation you can apply linear equations to. Use the news, internet, or other resources. You must cite the source of the information.

Chapter 3 Review

Chapter 3 Review

Below is the review video on Chapter 3 topics. Watch the video and then use the end of the video to correct your study guide. If you get any answers on the study guide wrong, see if you can find your mistake. Come to class tomorrow with questions!

There is one mistake in the video, on the discussion on slope r should equal 3.
