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. Horizontal line






2. No fraction or decimal






3. A=a it is what it is






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






5. Put is simplest form






6. 'Points' from side to side






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






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






9. e.g x






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






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






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






13. ROW x COLUMN






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






15. Vertical line






16. Hard - brackets






17. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






18. Slope of 1/1 - through 0






19. Shaded area






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






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






22. y-y{2}=m(x-x{2})






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






24. Solid line






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






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






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






28. Opposite - reciprocal slopes






29. Dotted line






30. Substitute AND simplify






31. Whats worth






32. One or more solutions






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






34. mx+b=y






35. If IxI>5 then x>5 or x<-5






36. Shading goes down - or left






37. Same slopes






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






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






40. Set of ordered pairs (input and output)






41. Plug in vertices in objective function






42. [2x+3]=9 - [2x+3]=-9 write it both ways






43. 'Points' from BOTTOM to TOP






44. Change one equation with LCM (i think) and add up - cancelling one variable out






45. A=b - then b=a






46. Soft - parentheses






47. Intersecting points






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






49. Solve using every equation (use linear combination)






50. No solution
