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






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






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






4. A=a it is what it is






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






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






7. Hard - brackets






8. e.g x






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






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






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






12. 'Points' from side to side






13. x-value because its value is given






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






15. Function whose graph is a line






16. Shading goes down - or left






17. ROW x COLUMN






18. Solid line






19. Solve using every equation (use linear combination)

20. Whats worth






21. Dotted line






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






23. Plug in vertices in objective function






24. Intersecting points






25. Shading goes up - or right






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






27. Set of ordered pairs (input and output)






28. Put is simplest form






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






30. One or more solutions






31. No solution






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






33. Substitute AND simplify






34. [2x+3]=9 - [2x+3]=-9 write it both ways






35. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






36. 1 -2 -3...maybe 0






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






38. Shaded area






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






40. 'Points' from BOTTOM to TOP






41. mx+b=y






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






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






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






45. A=b - then b=a






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






47. Soft - parentheses






48. Slope of 1/1 - through 0






49. Opposite - reciprocal slopes






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