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. A=a it is what it is






2. No fraction or decimal






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






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






5. Soft - parentheses






6. Put is simplest form






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






8. mx+b=y






9. Shading goes down - or left






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






11. 'Points' from side to side






12. Set of ordered pairs (input and output)






13. Shaded area






14. Vertical line






15. 1 -2 -3...maybe 0






16. Intersecting points






17. Horizontal line






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






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






20. 'Points' from BOTTOM to TOP






21. No solution






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






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






24. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






27. Opposite - reciprocal slopes






28. e.g x






29. Dotted line






30. Whats worth






31. Solid line






32. One or more solutions






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






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






35. Substitute AND simplify






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






37. x-value because its value is given






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






39. Solve using every equation (use linear combination)






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






41. Function whose graph is a line






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






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






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






45. Slope of 1/1 - through 0






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






47. Hard - brackets






48. A=b - then b=a






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






50. Same slopes
