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. Shading goes up - or right






3. Substitute AND simplify






4. Horizontal line






5. A=a it is what it is






6. Set of ordered pairs (input and output)






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






8. No solution






9. 'Points' from BOTTOM to TOP






10. Shaded area






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






12. Plug in vertices in objective function






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






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






15. mx+b=y






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






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






18. Vertical line






19. Opposite - reciprocal slopes






20. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






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






24. Same slopes






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






26. Dotted line






27. Put is simplest form






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






29. One or more solutions






30. Solid line






31. Function whose graph is a line






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






33. Soft - parentheses






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






35. No fraction or decimal






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






37. A=b - then b=a






38. Slope of 1/1 - through 0






39. 'Points' from side to side






40. 1 -2 -3...maybe 0






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






42. ROW x COLUMN






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






44. A=b - then ac=bc






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






46. Solve using every equation (use linear combination)






47. e.g x






48. Hard - brackets






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






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