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. One or more solutions






2. e.g x






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






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






5. ROW x COLUMN






6. No fraction or decimal






7. Whats worth






8. Plug in vertices in objective function






9. Shading goes down - or left






10. Horizontal line






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






12. 'Points' from side to side






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






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






15. Same slopes






16. Solid line






17. Slope of 1/1 - through 0






18. A=a it is what it is






19. 1 -2 -3...maybe 0






20. Function whose graph is a line






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






22. A=b - then b=a






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






24. Hard - brackets






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






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






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






28. Soft - parentheses






29. 'Points' from BOTTOM to TOP






30. Set of ordered pairs (input and output)






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






32. Shading goes up - or right






33. A=b - then ac=bc






34. Intersecting points






35. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






36. Opposite - reciprocal slopes






37. x-value because its value is given






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






39. Vertical line






40. Solve using every equation (use linear combination)

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






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






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






44. Substitute AND simplify






45. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






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






49. Dotted line






50. Put is simplest form
