92% or higher on the next exam.  Students 1-8 scored

the following on the exam:

 

             86, 91, 98, 83, 97, 89, 99, and 96

Test Hint: Perimeter means you need to add up all the

sides, so you are being tested on distributing and

Find the length of a rectangle with perimeter 30 meters

and width 4 meters.

 

l =
P = 2l + 2w

Test Hint: You are being tested on evaluating an

equation. You can either use your store feature

on your calculator or plug the equation into your

y = screen and use the table feature to solve using

the x value they gave you. Use whatever method

works best for you.

In the quadratic equation x2 - x + c = 0, c represents

an unknown constant. If x = 3 is one of the solutions

to this equation, what is the value of c?

c =

Test Hint: Place the equation for nonmembers in y1

and place the equation for members in y2 , then use

the table feature to find where the two equations

equal each other. The unknow variable is the number of

videos a customer will rent, therefore the x-value

represents the number of rented videos.

The is the same when a customer rents

Suppose a video store charges nonmembers $4 to rent

each video.  A store membership costs $21 and

members pay only $2.50 to each video. For what

number of videos is the cost the same?

videos.

Test Hint: Remember there will be a variable rate that

is connected to the x - value and a fixed rate that will

either be added or subtracted to the end of the equation.

To identify the variable rate look for words such as:

                          Each         A         Per

Denise's cell phone plan is $29.95 per month plus

$0.10 per minute.  Denise's cell phone bill is $99.95.

For how many minutes was she billed?

Write the equation out and then solve using the

two - step method.

She was billed for
minutes.
Find the product (-2x) (x2 - 3x + 9)
F. -2x3 - 3x + 9
G. -2x3 - 6x2 + 18x
H. -2x3 - 6x2 - 18x
J. -2x3 + 6x2 - 18x

Please feel free to take this practice test as many

times as you need.  I will have to reset the practice

exam for you, so come by during tutorials or

before / after class.
