Assume that all variables represent positive numbers. Thus, no absolute value signs will be needed: V-125 b) Simplify each of the following into one fraction that is reduced to lowest terms 7/27x + V8x* 361x c) Write in radical notation and simplify if possible: 25%2 Question 9-Through (-1, 5) with slope in = -1. a) Find the equation of the following lines. Write your answer in slope-intercept form. Show all work. b) What is the slope of any line perpendicular to that in part (a)? Explain. Question 10 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. Question 11 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?
