Algebra Formulas

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






2. Shaded area






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






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






5. No solution






6. Set of ordered pairs (input and output)






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






8. Hard - brackets






9. A=b - then b=a






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






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






12. 1 -2 -3...maybe 0






13. Dotted line






14. 'Points' from side to side






15. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






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






19. Shading goes down - or left






20. Opposite - reciprocal slopes






21. Soft - parentheses






22. Solve using every equation (use linear combination)

23. e.g x






24. Same slopes






25. Put is simplest form






26. 'Points' from BOTTOM to TOP






27. Vertical line






28. Intersecting points






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






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






31. Shading goes up - or right






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






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






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






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






36. One or more solutions






37. Plug in vertices in objective function






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






39. A=a it is what it is






40. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






41. Substitute AND simplify






42. ROW x COLUMN






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






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






45. Whats worth






46. Solid line






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






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






49. Function whose graph is a line






50. Horizontal line
