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. Slope of 1/1 - through 0






2. Shaded area






3. Intersecting points






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






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






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






7. Plug in vertices in objective function






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






9. 'Points' from BOTTOM to TOP






10. Horizontal line






11. mx+b=y






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






13. Set of ordered pairs (input and output)






14. Solve using every equation (use linear combination)

15. Put is simplest form






16. A=b - then ac=bc






17. Same slopes






18. [2x+3]=9 - [2x+3]=-9 write it both ways






19. A=a it is what it is






20. Shading goes down - or left






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






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






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






24. No solution






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






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






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






29. ROW x COLUMN






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






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






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






33. Solid line






34. Hard - brackets






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






36. Function whose graph is a line






37. Vertical line






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






39. Shading goes up - or right






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






41. e.g x






42. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






43. Opposite - reciprocal slopes






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






45. x-value because its value is given






46. A=b - then b=a






47. 'Points' from side to side






48. No fraction or decimal






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






50. Soft - parentheses
