Question 1 Determine the value:
Question Simplify and write the final answer without negative exponents:
Question 3 Add the following polynomials:
(a b)+ (2a 3a) (4b 2a) b
Question 5 Factor completely:
y4 6y3 9y
Question 6 Simplify and reduce to lowest terms:

b) What is the slope of any line perpendicular to that in part (a)? Explain.
a) Sketch the graph of the equation 2y + 3X- 1. Show all work.
b) What is the slope of the line in part (a)? Use your graph and the slope of this line to briefly explain the
meaning of slope.
Your company has purchased a $12,000 machine that has a useful life of 8 years. The salvage value of the
machine at the end of 8 years is $2,000. (Hint: on the y-axis indicate the value and on the x-axis the
years.) Write: a linear equation that describes the book value of the machine each year. What is the book
value of the machine at the end of year 4?
