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. Hard - brackets






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






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






4. [2x+3]=9 - [2x+3]=-9 write it both ways






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






6. Vertical line






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






8. Function whose graph is a line






9. Shading goes up - or right






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






11. Dotted line






12. 'Points' from BOTTOM to TOP






13. Same slopes






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






15. mx+b=y






16. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






18. A=b - then ac=bc






19. Plug in vertices in objective function






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






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






22. No solution






23. A=b - then b=a






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






25. One or more solutions






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






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






28. Opposite - reciprocal slopes






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






30. Solve using every equation (use linear combination)






31. Shaded area






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






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






34. 1 -2 -3...maybe 0






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






36. e.g x






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






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






39. Set of ordered pairs (input and output)






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






41. ROW x COLUMN






42. A=a it is what it is






43. Whats worth






44. Put is simplest form






45. Shading goes down - or left






46. x-value because its value is given






47. Substitute AND simplify






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






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






50. Solid line
