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. Shading goes up - or right






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






3. Set of ordered pairs (input and output)






4. Slope of 1/1 - through 0






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






6. No solution






7. Same slopes






8. No fraction or decimal






9. Horizontal line






10. A=b - then b=a






11. Plug in vertices in objective function






12. 1 -2 -3...maybe 0






13. One or more solutions






14. Solid line






15. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






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






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






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

23. Vertical line






24. Shading goes down - or left






25. Whats worth






26. Shaded area






27. e.g x






28. A=a it is what it is






29. [2x+3]=9 - [2x+3]=-9 write it both ways






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






31. Soft - parentheses






32. Put is simplest form






33. ROW x COLUMN






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






35. Solve using every equation (use linear combination)






36. Substitute AND simplify






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

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






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






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






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






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






47. A=b - then ac=bc






48. mx+b=y






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






50. Intersecting points
