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. Same slopes






2. A=a it is what it is






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






4. e.g x






5. A=b - then b=a






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






7. 1 -2 -3...maybe 0






8. 'Points' from BOTTOM to TOP






9. Hard - brackets






10. ROW x COLUMN






11. Function whose graph is a line






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






13. Substitute AND simplify






14. Solid line






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






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






17. No fraction or decimal






18. Intersecting points






19. Vertical line






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






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






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






23. Shading goes down - or left






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






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






26. mx+b=y






27. Slope of 1/1 - through 0






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






29. [2x+3]=9 - [2x+3]=-9 write it both ways






30. Shading goes up - or right






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






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






33. One or more solutions






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






35. Opposite - reciprocal slopes






36. Whats worth






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






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






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






40. 'Points' from side to side






41. Shaded area






42. Set of ordered pairs (input and output)






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






44. Soft - parentheses






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






46. Put is simplest form






47. Horizontal line






48. x-value because its value is given






49. Plug in vertices in objective function






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