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. A=a it is what it is






2. Soft - parentheses






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






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






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






6. 'Points' from side to side






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






8. Plug in vertices in objective function






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






10. Shading goes down - or left






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






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






13. A=b - then b=a






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






15. Same slopes






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






17. Shading goes up - or right






18. Whats worth






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






20. [2x+3]=9 - [2x+3]=-9 write it both ways






21. Opposite - reciprocal slopes






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






23. e.g x






24. Intersecting points






25. Dotted line






26. Solve using every equation (use linear combination)






27. ROW x COLUMN






28. One or more solutions






29. Hard - brackets






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






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






32. A=b - then ac=bc






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






34. Put is simplest form






35. mx+b=y






36. Horizontal line






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






38. Substitute AND simplify






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






40. x-value because its value is given






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






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






43. Vertical line






44. Shaded area






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






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






47. Set of ordered pairs (input and output)






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






49. No fraction or decimal






50. 'Points' from BOTTOM to TOP
