Chapter 3 Warm-ups

Section 3-1 Part I Warm-upUSE 2 BOXES!

Solve the following equations1) 8x + 7 = 5x + 16

2) 4(3x – 2) = 8(2x + 3)

3)

4) 3(x + 4) = 33

Section 3-1 Part II Warm-UpUse 1 Box

Are the following equations in standard form? If so, write “yes”, if not, re-write the equations in standard form1. y = 2x + 52. x = 4y – 83. 2x + 5y = 34. 6 = -x + 7y5. 8 – y = 3x

Section 3-1 Part III Warm-upUse 2 Boxes

Using the following equations:a) Find the x and y interceptsb) Graph using the intercepts

1) 5x + 10y = 202) x – 3y = 63) x = 5y + 5 (Be careful on this one!)
