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. Hard - brackets






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






3. Horizontal line






4. Shading goes down - or left






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






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






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






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






9. 'Points' from side to side






10. Set of ordered pairs (input and output)






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






12. e.g x






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






14. [2x+3]=9 - [2x+3]=-9 write it both ways






15. x-value because its value is given






16. Function whose graph is a line






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






18. mx+b=y






19. No solution






20. Opposite - reciprocal slopes






21. 1 -2 -3...maybe 0






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






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






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






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






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






27. Plug in vertices in objective function






28. A=b - then ac=bc






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






30. ROW x COLUMN






31. Put is simplest form






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






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






34. Solve using every equation (use linear combination)

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






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






37. 'Points' from BOTTOM to TOP






38. Same slopes






39. Shaded area






40. No fraction or decimal






41. Solid line






42. Intersecting points






43. Whats worth






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






45. Substitute AND simplify






46. Dotted line






47. A=a it is what it is






48. Vertical line






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






50. Shading goes up - or right
