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. 'Points' from side to side






2. A=b - then b=a






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






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






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






6. Substitute AND simplify






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






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






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






10. Set of ordered pairs (input and output)






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






12. A=b - then ac=bc






13. Soft - parentheses






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






15. mx+b=y






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






17. ROW x COLUMN






18. Solid line






19. Shading goes down - or left






20. Solve using every equation (use linear combination)






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






22. [2x+3]=9 - [2x+3]=-9 write it both ways






23. e.g x






24. One or more solutions






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






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






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






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






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






30. 'Points' from BOTTOM to TOP






31. Vertical line






32. Hard - brackets






33. Slope of 1/1 - through 0






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






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






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






37. Intersecting points






38. Plug in vertices in objective function






39. Horizontal line






40. Shading goes up - or right






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






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






43. Dotted line






44. Put is simplest form






45. No fraction or decimal






46. Function whose graph is a line






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






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






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






50. x-value because its value is given
