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. A=a it is what it is






2. No fraction or decimal






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






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






5. Function whose graph is a line






6. A=b - then b=a






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






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






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






10. Same slopes






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






12. Solid line






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






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






15. Vertical line






16. e.g x






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






18. Shading goes up - or right






19. Dotted line

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






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






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






35. One or more solutions

37. mx+b=y






38. Soft - parentheses






39. Hard - brackets






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






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






42. Shading goes down - or left






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






44. Plug in vertices in objective function






45. 1 -2 -3...maybe 0
