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






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






3. Solve using every equation (use linear combination)


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






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






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






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






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






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






10. A=b - then b=a






11. Horizontal line






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






13. Substitute AND simplify






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






15. Vertical line






16. Intersecting points






17. ROW x COLUMN






18. No solution






19. Whats worth






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






21. One or more solutions






22. Opposite - reciprocal slopes






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






24. Shading goes down - or left






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

32. Hard - brackets






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






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






35. mx+b=y






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






37. x-value because its value is given






38. e.g x






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






40. Same slopes






41. Set of ordered pairs (input and output)






42. Solid line






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

45. Shaded area






46. A=a it is what it is






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






48. Put is simplest form
