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. Plug in vertices in objective function






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






3. A=b - then b=a






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






5. ROW x COLUMN






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






7. Horizontal line






8. Opposite - reciprocal slopes






9. Whats worth






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






11. Shaded area






12. No fraction or decimal






13. No solution






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






15. e.g x






16. Solid line






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






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






19. Slope of 1/1 - through 0






20. Same slopes






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






22. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






23. 'Points' from side to side






24. x-value because its value is given






25. [2x+3]=9 - [2x+3]=-9 write it both ways






26. Hard - brackets






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






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






29. Shading goes down - or left






30. Set of ordered pairs (input and output)






31. Shading goes up - or right






32. Function whose graph is a line






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






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






35. One or more solutions






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






37. Soft - parentheses






38. Intersecting points






39. Solve using every equation (use linear combination)


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






41. Vertical line






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






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






44. Substitute AND simplify






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






46. 'Points' from BOTTOM to TOP






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






48. Dotted line






49. Put is simplest form






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