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






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






3. Slope of 1/1 - through 0






4. One or more solutions






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. Horizontal line






7. 'Points' from BOTTOM to TOP






8. Same slopes






9. Plug in vertices in objective function






10. Opposite - reciprocal slopes






11. Shaded area






12. ROW x COLUMN






13. Solve using every equation (use linear combination)






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






15. No solution






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






17. Set of ordered pairs (input and output)






18. 'Points' from side to side






19. Vertical line






20. Substitute AND simplify






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






22. Solid line






23. e.g x






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






25. Dotted line






26. x-value because its value is given






27. Shading goes down - or left






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






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






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






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






32. A=a it is what it is






33. mx+b=y






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






35. 1 -2 -3...maybe 0






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






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






38. [2x+3]=9 - [2x+3]=-9 write it both ways






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






40. A=b - then ac=bc






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






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






43. Function whose graph is a line






44. Put is simplest form






45. A=b - then b=a






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






47. Shading goes up - or right






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






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






50. Soft - parentheses
