# Algebra II Chapter 1

### Terms for SHS Chapter 1 Algebra II Test

Question | Answer |
---|---|

Associative Property | (a + b) + c = a + (b + c) (ab)c = a(bc) You can change the groups (doesn't change the order of the numbers) |

Commutative Property | a+b = b+a (You can replace a+b with b+a) ab = ba (You can replace ab with ba) |

Identity Property | a + 0 = a (When you ADD 0 you get the identical value.) a x 1 = a (When you X by 1 you get the identical value.) |

Inverse Property | a + (-a) = 0 (Opposites are inverses.) a x 1/a = 1 (Reciprocals are inverses.) |

Distributive Property | a(b + c) = ab + ac (a + b)c = ac + bc |

To convert miles to feet | multiply by 5280 feet / 1 mile |

To convert hours to minutes | Multiply by 60 min / 1 hour |

|2x + 3| = 7 | 2x + 3 = 7 OR -(2x + 3) = 7 |

|3x - 1| < 5 | 3x - 1 < 5 AND -(3x - 1) < 5 Shortcut: -5 < 3x - 1 < 5 |

|6x - 3| > 21 | 6x - 3 > 21 OR -(6x - 3) > 21 Shortcut: 6x - 3 > 21 OR 6x - 3 < -21 |

What is the formula for distance | d = r t |

Solve: 5m - 2 = -m - 2 | m = 0 |

Solve for x: 3xy + x = 12 | x = 12/(3y + 1) |
