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. Put is simplest form






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






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






4. One or more solutions






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






6. 'Points' from side to side






7. Whats worth






8. Hard - brackets






9. Dotted line






10. Horizontal line






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






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






13. Solve using every equation (use linear combination)

14. ROW x COLUMN






15. 'Points' from BOTTOM to TOP






16. Substitute AND simplify






17. Plug in vertices in objective function






18. A=a it is what it is






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






20. Opposite - reciprocal slopes






21. A=b - then b=a






22. x-value because its value is given






23. e.g x






24. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






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






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






29. mx+b=y






30. No fraction or decimal






31. Shading goes up - or right






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






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






34. Shaded area






35. Soft - parentheses






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






37. 1 -2 -3...maybe 0






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






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






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






41. No solution






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






43. Ax+By=C (letters are real - not zero)






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






45. Set of ordered pairs (input and output)






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






47. Same slopes






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






49. A=b - then ac=bc






50. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3
