Week 13 HW— January 9/10

first week back from winter break - we have a Monday session from 10-12 on 1/15. You don’t need to finish all your homework by then but having done most of it is how you’ll get the most out of this session.

Resource pages including answers are posted - 10:50 Friday am

Concepts: Direct variation word problems, compound and absolute value inequalitites introduction, introduction to systems of equations.

Day 1: Tuesday's HW

• Prepare to resubmit your final exam on Wednesday. You will have 45 minutes to work on problems you missed. Use your study time this afternoon to review the types of problems you missed. You circled the types of problems you missed in class today and took notes on how to do similar problems. Your resubmittal is open notes/HW/CW and open book. So book mark sections in your textbook and make notes.

Days 2-4

Smart Studying

Correct any remaining errors on Final Exam using the solution key HERE This is after you have resubmitted your test to me during class for a second chance grading. Now you are correcting any remaining errors using the answer key and solutions. If you got 200/200 on the retake, you may skip this portion.) Do your corrections on a different piece of paper and staple that to the front of your test.

GREENIE… some students had time to start this in class. Finish at home

Complete the odd problems on the following pages. Answers to Greenie work are on a button above “Greene Answer Keys”

• Page 5 - Solving Equations with Fractions review - odds

• Page 6 - Solving Two step equations - use clearing decimals by multiplying by a factor of ten -odds

• Note Greenie work is Math 8 for those of you who are going to integrated math programs in HS. For everyone else it is review as well as a preview of some geometry.

Textbook Homework

PH 5-5 Direct Variation

• Read pg 263 Example 3. Do Check understanding for example 2 Writing an Equation for a Given Point

• Watch and take notes: Direct variation word problems with Joann (https://www.youtube.com/watch?v=0Oloi4o7MhE)

PH 3-5 Intro to Compound and Absolute Value Inequalities - we didn’t have time to do this in class so you’ll watch some of the videos below and read the section in the book.

Watch at least one resource video below and take notes.

• How to solve and graph compound inequalities Mario Math Tutoring 12 minutes

• How to write a compound inequality when you already have the graphs on the numberline Mario Math Tutoring 3 minutes

• How to conceptualize an absolute value inequality on the numberline and then solve for x with Mario

Read section 3-5 examples, then do p. 164 #5, 20, 24, 34

PH 9-3 Review Multiplying Binomials and Trinomials

 HW PH — Re-read section 9.3. You can decide whether you like the “swoopies” method to keep track of multiplying terms, FOIL (but that only works for binomials), or the horizontal method.

DO p. 470-1 #20, 33, 36, SQUARE 45

PH 3-6  CW Absolute Value in Inequalities

HW PH Read section 3-6 all examples. Do p. 167-169 Check understanding 1-4

BA 10.8 Systems of Equations

Go to Desmos’s graphing calculator

• Type in the equations of two lines which intersect (so not parallel) lines.) This is called a system of equations. Where do these two lines intersect? That point of intersection is the SOLUTION to this system equations.

• Now type in the equation of a line and a second equation that is actually the same line. Where do they intersect (or overlap)? How many solutions or points of intersection/overlapping do those lines — which are the same- have? That’s the solution to that system of equations

 REVIEW VIDEOS - NOTES OPTIONAL, but pause and do practice problems with the instructor

 Review video:  similar figures

• Similar Figures by Magic of Math

Review videos: unit rates & dimensional analysis

• Unit Rates | Solving Unit Rate Problems - Link fixed 1/15 4:25 Monday Math with Mr. J

• Solving Unit Rate Word Problems | Math with Mr. J

• Converting from miles/hr to feet/second is called unit conversion or dimensional analysis
