CLEP College Algebra: Algebra Principles

Subjects : clep, 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. Include composition and convolution

8. Symbols that denote numbers - letters from the end of the alphabet - like ...x - y - z - are usually reserved for the






9. Is a binary relation on a set for which every element is related to itself - i.e. - a relation ~ on S where x~x holds true for every x in S. For example - ~ could be 'is equal to'.






10. The relation of equality (=) is...reflexive: b = b; symmetric: if a = b then b = a; transitive: if a = b and b = c then a = c.






11. Is Written as a + b






12. If a < b and b < c






13. A






14. Involve only one value - such as negation and trigonometric functions.






15. Applies abstract algebra to the problems of geometry






16. Is an equation in which a polynomial is set equal to another polynomial.






17. An equivalent for y can be deduced by using one of the two equations. Using the second equation: Subtracting 2x from each side of the equation: and multiplying by -1: Using this y value in the first equation in the original system: Adding 2 on each s






18. () is the branch of mathematics concerning the study of the rules of operations and relations - and the constructions and concepts arising from them - including terms - polynomials - equations and algebraic structures.






19. 0 - which preserves numbers: a + 0 = a






20. 1 - which preserves numbers: a^1 = a






21. In which the specific properties of vector spaces are studied (including matrices)






22. If a < b and c < 0






23. Real numbers can be thought of as points on an infinitely long line where the points corresponding to integers are equally spaced called the






24. Parenthesis and other grouping symbols including brackets - absolute value symbols - and the fraction bar - exponents and roots - multiplication and division - addition and subtraction






25. Are called the domains of the operation






26. The values of the variables which make the equation true are the solutions of the equation and can be found through






27. If an equation in algebra is known to be true - the following operations may be used to produce another true equation:






28. Two equations in two variables - it is often possible to find the solutions of both variables that satisfy both equations.






29. A unary operation






30. Is an equation of the form log`a^X = b for a > 0 - which has solution






31. Means repeated addition of ones: a + n = a + 1 + 1 +...+ 1 (n number of times) - has an inverse operation called subtraction: (a + b) - b = a - which is the same as adding a negative number - a - b = a + (-b)
