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. Soft - parentheses






2. Substitute AND simplify






3. Intersecting points






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






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






6. Function whose graph is a line






7. One or more solutions






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






9. 1 -2 -3...maybe 0






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






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






12. Put is simplest form






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






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






15. A=b - then b=a






16. ROW x COLUMN






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






18. A=b - then ac=bc






19. Plug in vertices in objective function






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






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






22. No solution






23. Opposite - reciprocal slopes






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






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






26. Shading goes down - or left






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






28. Solve using every equation (use linear combination)


29. Horizontal line






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






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






32. [2x+3]=9 - [2x+3]=-9 write it both ways






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






34. e.g x






35. Set of ordered pairs (input and output)






36. Same slopes






37. 'Points' from BOTTOM to TOP






38. 'Points' from side to side






39. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






40. Dotted line






41. Hard - brackets






42. x-value because its value is given






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






44. A=a it is what it is






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






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






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






48. No fraction or decimal






49. Solid line






50. Shading goes up - or right
