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. Horizontal line






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






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






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






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






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






8. Opposite - reciprocal slopes






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






10. ROW x COLUMN






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






12. Vertical line






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






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






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






16. Set of ordered pairs (input and output)






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






18. Whats worth






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






20. Function whose graph is a line






21. Slope of 1/1 - through 0






22. Substitute AND simplify






23. Put is simplest form






24. Intersecting points






25. No fraction or decimal






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






27. Hard - brackets






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






29. Plug in vertices in objective function






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






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






32. Soft - parentheses






33. Shaded area






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






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






36. A=a it is what it is






37. One or more solutions






38. Solve using every equation (use linear combination)


39. [2x+3]=9 - [2x+3]=-9 write it both ways






40. 'Points' from side to side






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






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






43. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






44. e.g x






45. Solid line






46. 1 -2 -3...maybe 0






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






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






49. No solution






50. mx+b=y
