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. e.g x






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






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






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






5. x-value because its value is given






6. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






7. Horizontal line






8. Intersecting points






9. 'Points' from side to side






10. Opposite - reciprocal slopes






11. Shading goes up - or right






12. Put is simplest form






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






14. Plug in vertices in objective function






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






16. A=b - then ac=bc






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






18. Hard - brackets






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






20. Slope of 1/1 - through 0






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






22. Function whose graph is a line






23. Substitute AND simplify






24. Whats worth






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






26. [2x+3]=9 - [2x+3]=-9 write it both ways






27. Soft - parentheses






28. ROW x COLUMN






29. One or more solutions






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






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






32. Shaded area






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






34. 'Points' from BOTTOM to TOP






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






36. A=a it is what it is






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






38. Second step to linear combo. Fill in variable for whatever you solved for OR change equation to y= or x=






39. 1 -2 -3...maybe 0






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






41. No solution






42. A=b - then b=a






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






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






45. Shading goes down - or left






46. Solve using every equation (use linear combination)

47. Set of ordered pairs (input and output)






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






49. Dotted line






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