Hope you all had a good weekend. Your homework was to watch the video in the last post. I know we're not supposed to give homework on weekends but this seemed pretty important;)
Anyway, I'm hoping you are feeling confident with solving linear equations by graphing. It's a lot of work but the goal was to see how all the tools: grids, equations, tables & graphs interrelate.
As we've begun work on solving systems of linear equations I've gotten a resounding, "Wow, this is so much quicker!" True, but we still want to maintain a conceptual understanding of the conceptual process of finding a shared solution point.
Accordingly, your homework will include translation tasks (words to algebra) and two word problems.
Please watch this video of me solving #16 on your homework and then complete the following:
HW: pg 386 #s 8, 14, 15, 16
Then answer:
HW: pg 387 #s 25 & 26 (pay close attention to "The value of x is 4 times the value of y"
as you might write this as 4x = y which is incorrect.)
Watch the second video of me solving #29 starting with a grid and then using substitution (instead of tables & graphs) once I have the equations set up. Write down the notes from my work on # 29 and then solve your own word problem #30 using a grid to make your equations and then substitution.
HW: pg 387 #s 29 & 30
