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






2. Put is simplest form






3. Horizontal line






4. Plug in vertices in objective function






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






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






7. 'Points' from side to side






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






9. No fraction or decimal






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






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






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






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






14. Solid line






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






16. ROW x COLUMN






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






18. e.g x






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






20. x-value because its value is given






21. Whats worth






22. Shaded area






23. Set of ordered pairs (input and output)






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






25. Shading goes down - or left






26. Function whose graph is a line






27. Intersecting points






28. Hard - brackets






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






30. Vertical line






31. Opposite - reciprocal slopes






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






33. Dotted line






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






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






36. Same slopes






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






38. A=b - then ac=bc






39. Substitute AND simplify






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






41. Solve using every equation (use linear combination)

42. No solution






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






44. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






46. A=b - then b=a






47. Soft - parentheses






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






49. mx+b=y






50. 'Points' from BOTTOM to TOP
