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






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






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






4. Vertical line






5. Plug in vertices in objective function






6. Horizontal line






7. Shaded area






8. Substitute AND simplify






9. Slope of 1/1 - through 0






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






11. Opposite - reciprocal slopes






12. No fraction or decimal






13. A=a it is what it is






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






15. Soft - parentheses






16. 'Points' from side to side






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






18. Same slopes






19. [2x+3]=9 - [2x+3]=-9 write it both ways






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






21. 'Points' from BOTTOM to TOP






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






23. A=b - then ac=bc






24. Intersecting points






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






26. Hard - brackets






27. Solid line






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






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






30. x-value because its value is given






31. Solve using every equation (use linear combination)






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






33. Set of ordered pairs (input and output)






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






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






36. 1 -2 -3...maybe 0






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






38. Put is simplest form






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






40. No solution






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






42. One or more solutions






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






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






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






46. Shading goes down - or left






47. Dotted line






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






49. e.g x






50. A=b - then b=a
