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 grouping a+(b+c)=(a+b)+c






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






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






4. mx+b=y






5. No solution






6. Plug in vertices in objective function






7. 1 -2 -3...maybe 0






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






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






10. ROW x COLUMN






11. Shading goes up - or right






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






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






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






15. Solve using every equation (use linear combination)


16. Put is simplest form






17. 'Points' from BOTTOM to TOP






18. A=a it is what it is






19. Function whose graph is a line






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






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






22. Shaded area






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






24. Hard - brackets






25. Solid line






26. 'Points' from side to side






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






28. Opposite - reciprocal slopes






29. [2x+3]=9 - [2x+3]=-9 write it both ways






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






31. Horizontal line






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






33. Dotted line






34. Shading goes down - or left






35. Slope of 1/1 - through 0






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






37. x-value because its value is given






38. Intersecting points






39. A=b - then ac=bc






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






41. Set of ordered pairs (input and output)






42. A=b - then b=a






43. Whats worth






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






45. Substitute AND simplify






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






47. No fraction or decimal






48. e.g x






49. One or more solutions






50. Vertical line
