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






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






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






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






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






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






7. One or more solutions






8. Intersecting points






9. Opposite - reciprocal slopes






10. Function whose graph is a line






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






12. x-value because its value is given






13. Hard - brackets






14. Slope of 1/1 - through 0






15. 1 -2 -3...maybe 0






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






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






18. A=a it is what it is






19. Substitute AND simplify






20. Horizontal line






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






22. 'Points' from side to side






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






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






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






26. Shaded area






27. mx+b=y






28. Same slopes






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






30. Whats worth






31. Shading goes down - or left






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






33. No solution






34. Plug in vertices in objective function






35. 'Points' from BOTTOM to TOP






36. Solid line






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






38. Dotted line






39. A=b - then ac=bc






40. Put is simplest form






41. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






43. e.g x






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






45. No fraction or decimal






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






47. Soft - parentheses






48. Solve using every equation (use linear combination)

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






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