Subjects : math, algebra
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. If IxI>5 then x>5 or x<-5






2. mx+b=y






3. Horizontal line






4. Set of ordered pairs (input and output)






5. Function whose graph is a line






6. Solve for (3x-4)(x+5)






7. Dotted line






8. Same slopes






9. A=b - b=c - then a=c






10. Whats worth






11. Set of all FIRST coordinates of the ordered pairs e.g. x (x -y)(input value - abscissa)






12. Put is simplest form






13. A relation in which each element of the domain is paired with one element in the range (no repeated x - however y can repeat)






14. A=b - then ac=bc






15. # set (2 -3) in x+1=y - 2+1=3






16. x-value because its value is given






17. Rectangular array of #s written w/brackets (classified by # of numbers in row and column e.g. 3x3)






18. Hard - brackets






19. A=a it is what it is






20. 1 -2 -3...maybe 0






21. Change of grouping a+(b+c)=(a+b)+c






22. Substitute AND simplify






23. One or more solutions






24. A=b - then b=a






25. Set might require positive integers - natural #s - positive reals - etc.






26. e.g x






27. f(x -y)=x + y






28. Relations do not have all points in common e.g diff. lines that may intersect






29. Correct result - but doesn't work in equation






30. Opposite - reciprocal slopes






31. Relations have all points in common e.g same line






32. Original status a+0=a - ax1=a






33. [2x+3]=9 - [2x+3]=-9 write it both ways






34. Function in mx+b=y form whose graph is a line






35. Undoes operation a+(-a)=0






36. Vertical line






37. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






38. Intersecting points






39. 'Points' from side to side






40. Shading goes up - or right






41. Plug in vertices in objective function






42. Soft - parentheses






43. No fraction or decimal






44. y-value - because its value depends on the x-value






45. Solid line






46. Change of order a+b+c=a+c+b






47. Slope of 1/1 - through 0






48. 'Points' from BOTTOM to TOP






49. Set of all SECOND coordinates of the ordered pairs e.g. y (x -y)(output value - ordinate)






50. No solution
