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






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






4. Put is simplest form






5. Solve using every equation (use linear combination)

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






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






8. Intersecting points






9. Shading goes down - or left






10. Hard - brackets






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






12. One or more solutions






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






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






15. Whats worth






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






17. Soft - parentheses






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






19. Plug in vertices in objective function






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






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






22. Substitute AND simplify






23. No solution






24. Shading goes up - or right






25. Shaded area






26. e.g x






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






28. Horizontal line






29. Dotted line






30. x-value because its value is given






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






32. Function whose graph is a line






33. Solid line






34. ROW x COLUMN






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






36. mx+b=y






37. 'Points' from BOTTOM to TOP






38. [2x+3]=9 - [2x+3]=-9 write it both ways






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






40. A=a it is what it is






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






42. Same slopes






43. Slope of 1/1 - through 0






44. A=b - then ac=bc






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






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






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






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






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






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