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






2. One or more solutions






3. mx+b=y






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






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






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






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






8. 'Points' from side to side






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. Set of ordered pairs (input and output)






11. No fraction or decimal






12. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






13. Function whose graph is a line






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






15. Whats worth






16. x-value because its value is given






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






18. 'Points' from BOTTOM to TOP






19. Solid line






20. Slope of 1/1 - through 0






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






22. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






25. Horizontal line






26. Opposite - reciprocal slopes






27. No solution






28. Shading goes up - or right






29. Shaded area






30. Plug in vertices in objective function






31. ROW x COLUMN






32. A=b - then ac=bc






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






34. Same slopes






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






36. Intersecting points






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






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






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






40. Shading goes down - or left






41. Soft - parentheses






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






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






44. A=a it is what it is






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






46. 1 -2 -3...maybe 0






47. e.g x






48. Hard - brackets






49. A=b - then b=a






50. Solve using every equation (use linear combination)
