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






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






4. Hard - brackets






5. No fraction or decimal






6. One or more solutions






7. Soft - parentheses






8. Opposite - reciprocal slopes






9. 'Points' from BOTTOM to TOP






10. Shaded area






11. [2x+3]=9 - [2x+3]=-9 write it both ways






12. Solid line






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






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






15. Plug in vertices in objective function






16. Function whose graph is a line






17. Shading goes up - or right






18. mx+b=y






19. Set of ordered pairs (input and output)






20. Intersecting points






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






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






23. A=b - then b=a






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






25. Put is simplest form






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






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






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






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






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






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






32. Dotted line






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






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






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






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






37. Solve using every equation (use linear combination)

38. Substitute AND simplify






39. Slope of 1/1 - through 0






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






41. Horizontal line






42. e.g x






43. ROW x COLUMN






44. Shading goes down - or left






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






46. Same slopes






47. 'Points' from side to side






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






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






50. Vertical line
