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






2. A=a it is what it is






3. ROW x COLUMN






4. Solid line






5. Shading goes up - or right






6. Put is simplest form






7. Plug in vertices in objective function






8. x-value because its value is given






9. e.g x






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






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






12. A=b - then ac=bc






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






14. One or more solutions






15. Slope of 1/1 - through 0






16. 1 -2 -3...maybe 0






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






18. A=b - then b=a






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






20. 'Points' from BOTTOM to TOP






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






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






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






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






25. mx+b=y






26. Set of ordered pairs (input and output)






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






28. Same slopes






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






30. Shading goes down - or left






31. Vertical line






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






33. No solution






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






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






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






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






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






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

41. Horizontal line






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






43. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






44. Hard - brackets






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






46. Shaded area






47. Substitute AND simplify






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






49. Function whose graph is a line






50. 'Points' from side to side
