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






2. e.g x






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






4. Horizontal line






5. A=b - then b=a






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






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






8. No solution






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






10. Put is simplest form






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






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






13. Shading goes up - or right






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






15. A=b - then ac=bc






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






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






18. x-value because its value is given






19. ROW x COLUMN






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






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






22. A=a it is what it is






23. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






24. Substitute AND simplify






25. Dotted line






26. Slope of 1/1 - through 0






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






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






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






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






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






32. Shaded area






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






34. mx+b=y






35. Plug in vertices in objective function






36. 'Points' from BOTTOM to TOP






37. Whats worth






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






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






40. Hard - brackets






41. Soft - parentheses






42. No fraction or decimal






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






44. Vertical line






45. One or more solutions






46. 'Points' from side to side






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






48. Opposite - reciprocal slopes






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






50. Solve using every equation (use linear combination)
