Here Are Your Questions

Try these out.

1. Where does the graph of -7y + 21x + 14 = 0 cross the y-axis?
2. A company makes cement using a water to cement ratio of 11 to 20. How many parts of water should be added to 300 parts of cement?

Good luck!

Looking for a Hint?

Here's a good question:

The equation h = -16 t^2 +56t + 32 describes the height h, in feet, of a ball t seconds after it is thrown from the balcony of a building. Sketch the graph of the equation. Then use the equation and the graph to tell all you can about the situation. You can write a paragraph but you may also use math notation.

Make sure you know the compound interest formula.

Almost Done!

You are almost finished and have learned much this year. Be sure to study hard for your algebra test. It will contain between 40 and 50 questions.

Check back here for hints.

Equations of Lines

If you are asked to find an equation for a line, immediately write down y = mx + b because that's where you are headed. Sometimes you are given a point and a slope; other times you are given two points. That's all the information you need.

If you are given a graph and need to read points, make sure you are 100% accurate when you read the coordinates. Sometimes, if the graph is very clear, you can read the y-intercept and count off the slope, like you did last night.

Check out this website. It explains point-slope form (NOT slope-intercept form) for the equation of a line. That's what tonight's homework is about. The website uses (x sub 1, y sub 1) instead of (h, k) for the given point.

Homework:

• Finish Lesson 6-4
• Complete Covering the Ideas in 6-5.

More Slope!

It's so important...you can never get enough practice with slope. Work carefully tonight.

Homework: (to be finished before Glee)

• Lesson 6-3, Covering the Ideas and Applying.

Slope

I found a nice lesson in coolmath for you. It's always a good idea to read about a math concept a second way.

Remind me to give you the Lesson Masters

Homework:

• Be sure to finish all of Lesson 6-1.
• Lesson 6-2, Covering the Ideas.

Today is.....

Have you googled today? What did you notice?

Is it just coincidence? Albert Einstein's birthday is today too!

Would you like to hear what the digits of pi translated to music sounds like? Listen to tubular bells. You might also like to try some art based on the digits of pi on the same site.

Homework:
Did you finish all of Lesson 5-2?

I think my calculators broken 8O!

Absolute Value & a Test

You may need to practice solving absolute value equations. This is a good website to help you understand better. Each one of you needs to comment on this website.

Homework: due onTuesday

• Chapter 4 Self Test - be sure you correct it.
• Lesson Master 4-9A. Check your answers.
• Test on Wednesday.

Did I Forget to Give You Homework?

You can work on the three Lesson Masters, 4-4, 4-5, and 4-6. If you want to get a head start on this weekend's homework, do Lesson 4-8, Review. That will also give you some more practice for the quiz tomorrow, especially questions 20-22.

Now that you've shoveled snow...

you need to check the answers to your algebra homework. The odds are in the back of the book. If you have questions, ask them in a comment.

Homework:
Finish Applying and Review in Lesson 4-4. I'll check back later.

Wasn't the Super Bowl great?

It's Still Snowing!

After you shovel the walk for your parents, you can start on your homework for Monday. How many of you are sure we won't be back in school until Wednesday?

Homework:

1. Lesson 4.3, finish up Applying and Review. This is for Monday (even though you don't have math on Monday).
2. Lesson 4-4, Covering.

Ask questions. I'll check back later. I'll also post the answers so you can check them. Show all work.

Has anyone in class lost power? I did but only for a short time in the middle of the night. A tree in my back yard fell over but fortunately only damaged a fence.

Snow Day Homework.

Hope you all had fun. I sure did. Rosie likes catching snowballs in her mouth!

Homework: Lesson 4-2, Review. It's only six questions.

Percent Equations

You need to learn to write equations to help you solve problems with percents. Be careful with discounts!
Homework:
Lesson 4-1, Covering.

Your Test Is Wednesday

I will return your quizzes tomorrow and answer questions. We will start Chapter 4.

Don't Forget Math

You need to do the Review in Lesson 3-8. I expect your work to be perfect.

Solving Inequalities

Be very careful when you are solving inequalities. You are using the Multiplication Property of Inequality (not equality) and that property has two parts.

Homework:

1. Finish the rest of Lesson 3-6.
2. Be sure to bring your Lesson Masters to class tomorrow.

Check Your Lesson Masters!

Go to the 7-8 Math Page to find the answer keys.

Your homework is Lesson 3-5, Covering. You need to show all your work for numbers 1-10.

Solving ax + b = c.

Homework:

1. Lesson 3-4, Covering. Be sure you show all your work for problems 6-13.
2. Quiz on Friday - Lessons 3-1 through 3-3
