Hey, 8th Graders...Solving Linear Equations by Graphing

The first video helps you set up the problem. The next video helps you solve for y. To find the intersection point, we have been using the graphing calculator. Remember that y min and x min is zero. The y max and x max is higher than the highest y-intercept in your problem.

Honors Algebra: Solving An Equation by Grouping

Hi, everyone. I found this video on YOUTUBE!

Remember that: Area of a circle is (pi)x(radius)squared; Area of a rectangle is (length)x(width); Area of a triangle is .5(base)x(height); Perimeter of a rectangle is 2(length) + 2(width) Watch the video on solving a geometry problem. Do pg.585 #49-51. Copy the pictures, show your work, answer the problem. Now after completing that, solve this next problem. You have a rectangular yard whose area is x squared plus 32x plus 231. What are the dimensions of the rectangular yard? What if you knew that x equaled 10, what are the dimensions of the yard and the area of the yard? Turn in all of your work, neatly, on April 8, 2013.

1. Find a relative that has a cell phone. Ask them about the initial cost of the cell phone and the charge per minute. Create an equation based on the information calling it C, in the form: C = mx + b. Find a different relative that has a cell phone. Ask them about their initial cost of the cell phone and the charge per minute. Create a second equation based on the information calling it C'', in the form: C'' = mx + b. 2. Watch the video below. 3. Just as we did in class, set the two equations equal to each other, find the value of x (in minutes). 4. Now, take that value of x and plug it into C or C'' to get the cost. 5. Create a graph and graph the two equations similar to Mr. Taylor's sample problem. Watch the video below for an idea of what to do.

1. Re read pg. 5 1.1 Walking Marathons and pg. 6 Problem 1.1 Finding and Using Rates. 2. Go outside. You are about to model the activity we did in class two weeks ago. Measure off a section of land or sidewalk. Record the distance (in units). Ask a friend to help you. Obtain a stopwatch (or some way to measure seconds). Record the time it takes to do from section to the far end of the section while walking. Now, repeat the process while running. 3. Now, watch the video below to figure out the next part of your extra credit. 4. Answer the following questions, remember D = r(t) or M = r(s): a) If you were walking at your rate, how far did you travel in 30 seconds? If you were running at your rate, how far did you travel in 30 seconds? b) If you were apart of a walkathon and charged $5 per unit you walked, how much money would you get if you walked for 60 seconds? How much money would you get if you ran for 60 seconds?
