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. 'Points' from side to side






2. Vertical line






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






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






5. Opposite - reciprocal slopes






6. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






7. A=b - then ac=bc






8. ROW x COLUMN






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






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






11. [2x+3]=9 - [2x+3]=-9 write it both ways






12. 'Points' from BOTTOM to TOP






13. Set of ordered pairs (input and output)






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






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






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






17. Dotted line






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






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






20. Function whose graph is a line






21. Slope of 1/1 - through 0






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






23. No fraction or decimal






24. Solid line






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






26. Intersecting points






27. Soft - parentheses






28. Substitute AND simplify






29. Hard - brackets






30. x-value because its value is given






31. 1 -2 -3...maybe 0






32. Same slopes






33. No solution






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






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






36. Solve using every equation (use linear combination)

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






38. A=b - then b=a






39. e.g x






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






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






42. A=a it is what it is






43. Shaded area






44. Plug in vertices in objective function






45. One or more solutions






46. Put is simplest form






47. Horizontal line






48. mx+b=y






49. Shading goes up - or right






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