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. A=b - then ac=bc






2. Substitute AND simplify






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






4. Hard - brackets






5. 1 -2 -3...maybe 0






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






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






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






9. A=b - then b=a






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






11. x-value because its value is given






12. Slope of 1/1 - through 0






13. [2x+3]=9 - [2x+3]=-9 write it both ways






14. Function whose graph is a line






15. e.g x






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






17. 'Points' from side to side






18. Whats worth






19. mx+b=y






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






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






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






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






24. Plug in vertices in objective function






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






26. Shaded area






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

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






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






33. Intersecting points






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






35. A=a it is what it is






36. Put is simplest form






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






38. ROW x COLUMN






39. Shading goes down - or left






40. 'Points' from BOTTOM to TOP






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






42. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






43. Horizontal line






44. Same slopes






45. Solid line

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






48. No solution






49. Set of ordered pairs (input and output)






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