I found a great website online that can help you study for math tests and quizzes. Try going to algebrahelp.com. You can do worksheets on exponents, graphing, and simplifying.
For problem 5b in lesson 2-7, I do not understand how to use the addition property of equality. The property requires "a" to equal "b", but there are no equivalent numbers in the problem. Does anybody have a tip?
O'reilly, a tip would be that, although there aren't any equivalent, since y-6=14, y=y-6+6 whcih uses the property (I can't think of it right now) that makes the cancel each other out, so change y-6=14 to 14-(-6)or 14+6 which gives you the answer. So put y=a and (-6)=b and 14=c, if (-b)+c=a, then (-a)+c=b. Does that answer your question, or did that not ,make any sense?
O'Reilly, I found an easier way to conduct this than Putrickm's way. I start off the same way, yet i add a few steps before. It helps me to visualize it. i right the original equation: y+(-6)=14. Then, i change it to subtraction: y-6=14. Afterwards, you add 6 to both sides [using the addition property of equality] so that it cancels out 6 on one side and so that you are still keeping it equivalent: y=y-6+6=14=6. So, you end up getting y=y+0=14=6. If you simplify that, you get y=20, which gets you to the end, or, the value of y!
Like I said I was going to comment on how long it took to do the math homework...15-17 minutes I forgot to time myself. AHC was great except my shadow was taking algebra 1 and it was nothing like what we are taking now. It was so much easier ( no offense to weisej) I remember scientific notation and numbers to the zeroith power from last year. I learned like an algorithm sort of thing for negative exponents 1/n to the absolute value of the exponent power. I did seem to catch on alot faster than some of the girls there though so I felt special. I really enjoyed the geometry class though. In geometry we went over the homework which had to do with naming steps with properties like I think it was the definition of congruency and right angle property and stuff like that. Ohh..bigredskinsfan27 I'll check out your website see if it helps sounds like it will. Thanks. See you tomorrow!!!
No you are not suposed to write a number sentence for number 12 in lesson 2-8. We just need to list all of the possibilities for "the number". For example 12a. I would put:
Zero times.....is eight.
or for 12b.
zero times......is zero (here would be a great place to put in a dominion for the variable or "a number" {x:x is a....number})

Is the homework lesson 2-5 Applying and 2-7 CTI or all of lesson 2-5 and applying & CTI in lesson 2-7?
The homework is to finish up lesson 2-5 and do #1-6 in Lesson 2-7.
Ok thanks.

For problem 12 in lesson 2-8 I don't understand what to do. Am I supposed to write out a number sentence?
