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. Horizontal line






2. Set of ordered pairs (input and output)






3. x-value because its value is given






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






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






6. Shaded area






7. One or more solutions






8. Put is simplest form






9. Shading goes up - or right






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






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






12. Same slopes






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






14. Soft - parentheses






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






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






17. Hard - brackets






18. ROW x COLUMN






19. A=b - then b=a






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






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






22. No solution






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






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






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






26. mx+b=y






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






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






29. Dotted line






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






31. Slope of 1/1 - through 0






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






33. Solve using every equation (use linear combination)

34. Whats worth






35. Plug in vertices in objective function






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






37. Intersecting points






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






39. A=b - then ac=bc






40. e.g x






41. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






42. Vertical line






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






44. Opposite - reciprocal slopes






45. Function whose graph is a line






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






47. Substitute AND simplify






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






49. No fraction or decimal






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