100

Evaluate

9 x [6 + (5 - 4)] = 

63

200

Evaluate

14 / (2 + 5) - 1 =

1

300

Evaluate

(32 - 12) / 5 = 

4

400

Evaluate

( 9 x 4) / (11 - 5) = 

4

500

Evaluate

(3 - 6 - 9) - [8 + (-4) - (-7)] = 

-23

Simplifying/Evaluating

100

Solve..

3x - 7 = 11 - 6x

x = 2

200

-8n + 3(4 + 9n)

19n + 12

300

-7(n + 3) - 8(1 + 8n)

-71n - 29

400

If x = 4   y = 3  and  z = 6

xy / z = 

4 x 3 / 6 = 2

500

If x = 7  and y = 6 and z = 2

2xz + 10 = 

2 x 7 x 2 = 28 + 10 = 38

Standard Form

100

Write in standard form...

y = -2x + 10

2x + y = 10

200

Write in standard form..

-2y = 5x + 7

5x + 2y = -7

300

Write in standard form..

2y = 1/2x + 10

x - 4y = -20

400

Write in standard form..

7y = 3/8x - 2

3x - 56y = 16

500

Write in standard form...

-2y = 10x + 17

10x + 2y = -17

Functions

100

Is this a function...

(3, 7) (2, 5) (1, 7) (0, 0)

Yes, all the x values are different

200

Evaluate the function... f(x) = 5x - 13

f(3) = 

2

300

Evaluate the function... g(x) = 12x - 28

g(-2) = 

-52

400

Graphing/Slope

100

What is the slope...

x = 9

m = undefined

200

Find the slope of a line with equation

y = -7x - 4

m = -7

300

Write in slope intercept form...

m = 1  (2,3)

y = 1x + 1

400
