Thursday, September 1

Geometry - We concluded our discussion of Sec. 1.2, focusing on what can and cannot be interpreted from a diagram (OK - location/placement of points; NOT OK - assuming specific length/measure/congruence/etc). Additionally, we discussed the processes needed to solve simple, single-variable equations algebraically. HW for Friday - Complete the algebra equation solving worksheet distributed in class.

Note: Hints for solving simple, single-variable equations:

Addition Property for = ... If a = b, then a + c = b + c
- It is OK to add equal quantities to both sides of an equation
- This also applies to subtraction

Multiplication Property for = ... If a = b, then a * c = b * c (where * means multiply)
- It is OK to multiply equal quantities to both sides of an equation
- This also applies to division

Distributive Property for Multiplication over Addition
a * ( b + c ) = a * b + a * c

Similarly, we Combine Like Terms in much the same way ...
x * z + y * z = ( x + y ) * z


Algebra 2 / Trig - We spent the day reviewing for Friday's quiz covering Sections 1.1 - 1.5. HW for Friday - Complete pgs 38 - 39 #3-19 (odd), #23-33 (odd), and #43-47 and pg 43 #1-17.

For additional practice for Friday's quiz, review problems on pgs. 76 - 77 and/or pg. S4 in your text.
