Simplify                                                                                   Write using standard notation:

30 + 12x - 16x2+ 35x + 22x2 - 45x - 73                                              2.18 x 104

 

 

 

Write using scientific notation                                            Multiply

            2,200                                                                             (2A ­ 9)(3A + 7)

 

 

 

Factor completely                                                                  Solve for the given variable

22x3  ­  11x2 +  44                                                                   5x2  ­  16x   + 3 =  0

 

 

 

 

 


 

Change to slope-intercept form

3y ­ 6x = 24

 

 

 

 

 

 

 

The sum of two numbers is five hundred thirty two. The difference between them is one hundred twenty six. What are the numbers?

 

 

 

 

 

 

 

 

 

Solve by substitution: 

 y = 3x + 1

 2x + y = 11

 

 

Solve by addition:

4x + 2y = 26

5x ­ 2y = 1

 

 

 

 

 

 

 

 

 

 

 

 

Let A = { 1, 2, 3, 4, 5 } , B = {-5, -3, -1, 1, 3 } and C = { -2, -1, 0, 1, 2}

Use roster notation for

      A Union C                                                   B Intersect A
