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






2. 'Points' from side to side






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






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






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






6. Set of ordered pairs (input and output)






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






8. x-value because its value is given






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






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






11. Horizontal line






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






13. Put is simplest form






14. Shaded area






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






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






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






18. Same slopes






19. Opposite - reciprocal slopes






20. [2x+3]=9 - [2x+3]=-9 write it both ways






21. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






22. Slope of 1/1 - through 0






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






24. Soft - parentheses






25. 'Points' from BOTTOM to TOP






26. Plug in vertices in objective function






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






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






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






30. Hard - brackets






31. One or more solutions






32. Whats worth






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






34. Substitute AND simplify






35. No fraction or decimal






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






37. Solid line






38. mx+b=y






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






40. e.g x






41. Vertical line






42. A=b - then b=a






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






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






45. Solve using every equation (use linear combination)






46. Intersecting points






47. Shading goes up - or right






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






49. Shading goes down - or left






50. Function whose graph is a line
