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=b - then b=a






2. Soft - parentheses






3. Solve using every equation (use linear combination)

4. Shading goes up - or right






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






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






7. Vertical line






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






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






10. Shaded area






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






12. One or more solutions






13. Slope of 1/1 - through 0






14. Opposite - reciprocal slopes






15. ROW x COLUMN






16. mx+b=y






17. Solid line






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






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






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






21. Substitute AND simplify






22. 'Points' from BOTTOM to TOP






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






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






25. 1 -2 -3...maybe 0






26. No solution






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






28. Hard - brackets






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






30. Put is simplest form






31. Shading goes down - or left






32. e.g x






33. Same slopes






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






35. Intersecting points






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






37. Whats worth






38. Function whose graph is a line






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






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






41. Set of ordered pairs (input and output)






42. x-value because its value is given






43. Horizontal line






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






45. A=b - then ac=bc






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






47. A=a it is what it is






48. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






50. No fraction or decimal
