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






2. Put is simplest form






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






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






5. Hard - brackets






6. Opposite - reciprocal slopes






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






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






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






10. Solid line






11. Substitute AND simplify






12. A=b - then ac=bc






13. x-value because its value is given






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






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






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






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






18. Shading goes down - or left






19. Function whose graph is a line






20. One or more solutions






21. mx+b=y






22. 'Points' from BOTTOM to TOP






23. Whats worth






24. A=a it is what it is






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






26. Shaded area






27. Vertical line






28. No solution






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






30. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






32. Plug in vertices in objective function






33. 'Points' from side to side






34. No fraction or decimal






35. Set of ordered pairs (input and output)






36. Soft - parentheses






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






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






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






40. Slope of 1/1 - through 0






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






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






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






44. Intersecting points






45. Solve using every equation (use linear combination)

46. A=b - then b=a






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






48. e.g x






49. Same slopes






50. ROW x COLUMN
