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. f(x -y)=x + y






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






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






4. e.g x






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






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






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






8. x-value because its value is given






9. Opposite - reciprocal slopes






10. Same slopes






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






12. Substitute AND simplify






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






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






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






16. Soft - parentheses






17. Intersecting points






18. A=b - then ac=bc






19. Function whose graph is a line






20. Set of ordered pairs (input and output)






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






22. No solution






23. Plug in vertices in objective function






24. Vertical line






25. Solve using every equation (use linear combination)

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






27. ROW x COLUMN






28. Horizontal line






29. Shading goes down - or left






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






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






32. mx+b=y






33. Solid line






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






35. Hard - brackets






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






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






38. Slope of 1/1 - through 0






39. A=b - then b=a






40. 1 -2 -3...maybe 0






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






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






43. One or more solutions






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






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






46. Shaded area






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






48. A=a it is what it is






49. Whats worth






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