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






2. Intersecting points






3. Dotted line






4. A=b - then ac=bc






5. A=a it is what it is






6. No fraction or decimal






7. No solution






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






9. Slope of 1/1 - through 0






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






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






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






13. ROW x COLUMN






14. 1 -2 -3...maybe 0






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






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






17. One or more solutions






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






19. Hard - brackets






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






21. Plug in vertices in objective function






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






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






24. 'Points' from BOTTOM to TOP






25. e.g x






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






27. Opposite - reciprocal slopes






28. Shaded area






29. Vertical line






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






31. 'Points' from side to side






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






33. Set of ordered pairs (input and output)






34. Function whose graph is a line






35. Put is simplest form






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






37. A=b - then b=a






38. Solid line






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






40. mx+b=y






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






42. Solve using every equation (use linear combination)

43. [2x+3]=9 - [2x+3]=-9 write it both ways






44. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






47. Shading goes down - or left






48. Shading goes up - or right






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






50. Horizontal line
