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-value - because its value depends on the x-value






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






3. Dotted line






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






5. [2x+3]=9 - [2x+3]=-9 write it both ways






6. Horizontal line






7. mx+b=y






8. x-value because its value is given






9. Plug in vertices in objective function






10. ROW x COLUMN






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






12. Soft - parentheses






13. Same slopes






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






15. Shading goes down - or left






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






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






18. 'Points' from BOTTOM to TOP






19. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






21. Hard - brackets






22. Shaded area






23. e.g x






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






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






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






27. A=b - then ac=bc






28. Intersecting points






29. Set of ordered pairs (input and output)






30. Solve using every equation (use linear combination)






31. No solution






32. Solid line






33. Vertical line






34. 1 -2 -3...maybe 0






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






36. A=a it is what it is






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






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






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






40. Slope of 1/1 - through 0






41. Opposite - reciprocal slopes






42. Substitute AND simplify






43. Put is simplest form






44. One or more solutions






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






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






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






48. No fraction or decimal






49. Shading goes up - or right






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