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. f(x -y)=x + y






2. Whats worth






3. No fraction or decimal






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






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






6. Solve using every equation (use linear combination)






7. One or more solutions






8. Slope of 1/1 - through 0






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






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






11. A=b - then ac=bc






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






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






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






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






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






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






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






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






20. Set of ordered pairs (input and output)






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






22. No solution






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






24. mx+b=y






25. Opposite - reciprocal slopes






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






27. x-value because its value is given






28. Shading goes down - or left






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






30. ROW x COLUMN






31. Function whose graph is a line






32. Intersecting points






33. Soft - parentheses






34. Plug in vertices in objective function






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






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






37. Dotted line






38. Solid line






39. Vertical line






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






41. Put is simplest form






42. Shaded area






43. [2x+3]=9 - [2x+3]=-9 write it both ways






44. Same slopes






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






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






47. 'Points' from side to side






48. Shading goes up - or right






49. 'Points' from BOTTOM to TOP






50. e.g x
