Final Exam 1. Arrange these numbers in order from least to greatest by changing all numbers to fraction form 33%, 0.3, , 0, -33%, -0.3, , -1/3,-33/100,-3/10,0,3/10,33/100,1/3 2. Convert to fraction. = 107/100 3. Calculate = 33 4. Calculate (-2) 3 = -8 5. Use the distributive property to remove the parentheses = x^3+7x^2+9x 6. Solve = x=7/13 7. Find x-intercept and y-intercept of the equation 7x + 5y = 20. 8. What is the slope of the line which pass through points (7, 3) and (9,2)? Slope=1/2 9. Convert 5x – 7y = 44 to slope-intercept form. What is the slope and y-intercept of this line? Slope=5/7 Y-intercept=-44/7 10. Find the equation of the line through (3, -2) that is perpendicular to the line 4x + 5y = 8? Please write the equation in standard form. 11. Graph the system of inequalities 5x – 2y < 10 x + 2y > -2 x – y > -4 12. Solve the system by graphing. x + 3y = -3 2x – y = 8 13. Solve the system by the substitution method. 4x + 3y = 5 (1) x = -4 x + 2y = 10 (2) y = 7 14. Solve the system by the additional method.

Unformatted text preview: 2x + 3y = 1 (1) x = 2 x – y = 3 (2) y = -1 15. Solve the system using your preferred method. (1) x = y/2 -3 (2) 2y + 3 16. Solve the system of equations using your preferred method: 2x – y = 2-4x + 2y = -4 No solution 17. Points A, B, and C are on the same line. The coordinates for A, B, C are (6, 1), (2, 2), and (x, 4). What is x? 18. A line with a slope of 2 and passes a point (4, 1). Please write the equation for this line in standard form. (standard form is Ax + By = C) 19. A line with a slope of 2 and passes a point (4, 1). Please write the equation for this line in slope-intercept form. (slope-intercept form is y = mx + b) 20. Solve the system of equations by substitution method: 3x – y = -3 6x – 2y = 6 No Solution The one’s highlighted in pink I could not get the graph program to work I am sorry I geuss I will be losing points for thought just thought I would tell why they were not done....
