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






2. Plug in vertices in objective function






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






4. Function whose graph is a line






5. x-value because its value is given






6. Set of ordered pairs (input and output)






7. Dotted line






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. Intersecting points






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






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






13. No fraction or decimal






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






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






16. Soft - parentheses






17. Solve using every equation (use linear combination)

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






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






20. Same slopes






21. mx+b=y






22. Shading goes up - or right






23. Vertical line






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






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






26. Shading goes down - or left






27. [2x+3]=9 - [2x+3]=-9 write it both ways






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






29. Put is simplest form






30. A=b - then b=a






31. 'Points' from side to side






32. A=b - then ac=bc






33. Hard - brackets






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






35. Whats worth






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






37. Opposite - reciprocal slopes






38. 'Points' from BOTTOM to TOP






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






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






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






42. A=a it is what it is






43. Substitute AND simplify






44. ROW x COLUMN






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






46. One or more solutions






47. e.g x






48. Solid line






49. Shaded area






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