HOMEWORK: p.432 #1

Evaluating expressions:
Rule: Substitute in the values of the variables
and use BEDMAS
Ex. 1 Evaluate y if x = -2:
y  3x  4 x  5
Ex. 2 Evaluate y if x = 3:
4x  3 y  9  3

HOMEWORK: p. 433 # 1

Rules:

Only LIKE TERMS may be added or subtracted
When multiplying or dividing, use exponent laws

Distributive Property:

 a(b+c)

= axb + axc
Foil:
 (a+b)(c+d)
= ac + ad + bc + bd
