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. Hard - brackets






2. Soft - parentheses






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






4. 1 -2 -3...maybe 0






5. Intersecting points






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






7. No fraction or decimal






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






9. Slope of 1/1 - through 0






10. Substitute AND simplify






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






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






13. Shading goes up - or right






14. A=a it is what it is






15. Whats worth






16. e.g x






17. Shaded area






18. Plug in vertices in objective function






19. A=b - then b=a






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






21. mx+b=y






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






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






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






25. A=b - then ac=bc






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






27. Shading goes down - or left






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






29. Solid line






30. Vertical line






31. One or more solutions






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






33. x-value because its value is given






34. 'Points' from side to side






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






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






37. Same slopes






38. Function whose graph is a line






39. No solution






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






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






42. [2x+3]=9 - [2x+3]=-9 write it both ways






43. ROW x COLUMN






44. Set of ordered pairs (input and output)






45. Opposite - reciprocal slopes






46. Put is simplest form






47. Solve using every equation (use linear combination)

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






49. Horizontal line






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