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. ROW x COLUMN






2. 'Points' from side to side






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






4. Shading goes up - or right






5. Hard - brackets






6. Substitute AND simplify






7. [2x+3]=9 - [2x+3]=-9 write it both ways






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






9. Dotted line






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






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






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






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






14. mx+b=y






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






16. Soft - parentheses






17. Put is simplest form






18. No fraction or decimal






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






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






21. No solution






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






23. 1 -2 -3...maybe 0






24. A=b - then ac=bc






25. 'Points' from BOTTOM to TOP






26. Whats worth






27. Shaded area






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






29. e.g x






30. One or more solutions






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






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






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






34. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






35. Vertical line






36. Slope of 1/1 - through 0






37. Solid line






38. Set of ordered pairs (input and output)






39. Intersecting points






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






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






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






43. Same slopes






44. Function whose graph is a line






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






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






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






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






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






50. A=b - then b=a
