1. Warm Up: Tuesday 11-27-12 Solve for x and justify each step:
a) 5x + 3 – 2x = 7 b) 9x – 12 = 8x – 3
Solve for “y”: ax + by = c
Simplify: (x – 3)²

2. Warm Up: Wednesday 11-28-12 Solve for x and justify each step:
a) 4y + 3(2y + 4) = 14 b) x – 12 = 3x – 12
Solve for “y”: 2x + 3y = c
Simplify: 2(x – 3)²

3. Warm Up: Thursday 11-29-12 Solve for x and justify each step:
a) 4y + 3(2 – 4y) = 14 b) x – 12 = x – 12
Solve for “y”: 4x – 4y = c
Find the area of the
shaded region:
x - 1
2x-5 x
3x + 5

4. Warm Up: Friday 11-30-12 Solve for x and justify each step:
2(x - 4) + x = b) 3x – 12 = x – 4 3
Solve for “y”: 2x + 4y = c
3. Simplify: 2(x – 3)2 + 1

5. Warm Up: Monday 11-19-12 Simplify: (-2x5y2)(3x4)
Simplify: (-3x5)(-2x³)²
6x4
Find the perimeter:
5x2 - 3
2x2
