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. Set of ordered pairs (input and output)






2. Same slopes






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. Plug in vertices in objective function






6. Whats worth






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






8. A=b - then ac=bc






9. Shading goes up - or right






10. [2x+3]=9 - [2x+3]=-9 write it both ways






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






12. 'Points' from side to side






13. Solid line






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






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






16. ROW x COLUMN






17. 'Points' from BOTTOM to TOP






18. Shaded area






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






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






21. Substitute AND simplify






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






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






24. e.g x






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






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






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






28. mx+b=y






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






30. No fraction or decimal






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






32. A=b - then b=a






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






34. Intersecting points






35. x-value because its value is given






36. Opposite - reciprocal slopes






37. No solution






38. Solve using every equation (use linear combination)


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






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






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






42. Dotted line






43. One or more solutions






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






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






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






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






48. Soft - parentheses






49. Slope of 1/1 - through 0






50. Shading goes down - or left
