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






2. A=a it is what it is






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






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






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






6. 'Points' from BOTTOM to TOP






7. Same slopes






8. No fraction or decimal






9. Whats worth






10. ROW x COLUMN






11. Solve using every equation (use linear combination)

14. Set of ordered pairs (input and output)






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






16. [2x+3]=9 - [2x+3]=-9 write it both ways

23. Solid line






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






25. Slope of 1/1 - through 0






26. Vertical line






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






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






29. No solution






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






31. Dotted line






32. Horizontal line






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






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






35. Hard - brackets






36. One or more solutions






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






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






39. e.g x






40. Shaded area






41. A=b - then b=a






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






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






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






45. 'Points' from side to side






46. A=b - then ac=bc






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






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