### The average annual tuition and fees at all 4-year institutions in the US in 1982 was $10,550 and in 2012 was $ 26,670. Let y be the average tuition and fees in the year x, where x = 0 represents the year 1982.

# Algebra: complete 4 problems

Please complete 4 problems.

- Tony wins $560,000 (after taxes) in the lottery and decides to invest half of it in a 7-year CD that pays 5.25% interest compounded monthly. He invests the other half in a money market fund that unfortunately turns out to average only 4.4% interest compounded annually over the 7-year period. How much money will he have altogether in the two accounts at the end of the 7-year period?

- The average annual tuition and fees at all 4-year institutions in the US in 1982 was $10,550 and in 2012 was $ 26,670. Let y be the average tuition and fees in the year x, where x = 0 represents the year 1982.

- a) Write a linear equation, in slope-intercept form, that models the growth in average tuition and fees at all 4-year institutions in the US in terms of the year x.
- b) Use this equation to predict the average tuition and fees at 4-year institutions in the US in the year 2030.
- c) Explain what the slope of this line means in the context of the problem.

- Given the following two linear equations, determine whether the lines are parallel, perpendicular, or neither. Show all work and explain your conclusion clearly.

4x - 5y = 15

5x+ 4y = 22

4. Find an equation of the line through (-1, 4), parallel to the line with equation

2x – 7y = 10. Write the new equation in point-slope form.

- Convert the equation of the new line found in problem #4 to standard form,

Ax + By = C, where A, B, and C are integers.
