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. Whats worth






2. A=b - then ac=bc






3. Horizontal line






4. Plug in vertices in objective function






5. e.g x






6. x-value because its value is given






7. Slope of 1/1 - through 0






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






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






10. Put is simplest form






11. One or more solutions






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






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






14. Shading goes up - or right






15. Same slopes






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






17. Intersecting points






18. Shading goes down - or left






19. Solid line






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






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






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






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






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






25. Hard - brackets






26. Solve using every equation (use linear combination)

27. Shaded area






28. Function whose graph is a line






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






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






31. mx+b=y






32. A=b - then b=a






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






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






35. Opposite - reciprocal slopes






36. Soft - parentheses






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






38. No fraction or decimal






39. Substitute AND simplify






40. 'Points' from BOTTOM to TOP






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






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






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






44. [2x+3]=9 - [2x+3]=-9 write it both ways






45. Dotted line






46. No solution






47. 'Points' from side to side






48. ROW x COLUMN






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






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