Question

Check out if I'm right
Plz explain..if u have a different answer

Answer 1

• The numerator has 3 terms.
• The denominator includes a coefficient of 2.

and possibly (check your definitions)

• The denominator includes a coefficient of 4.
• The numerator includes a coefficient of 3.

Explanation:

Apparently, the exercise is to count terms and identify coefficients.

A term is a constant or the product of a constant and some constellation of variables.

A coefficient is a multiplier of the variable(s) of interest. Any term or expression multiplying only 1 (not any expression involving the variable(s) of interest), may be called a "constant coefficient."

Consider the expression ...

... axy +bx +cy +d

If we consider the variables x and y to be the variables of interest, then "d" is a "constant coefficient" and "a", "b", and "c" are the coefficients in the first three terms.

If we consider y to be the variable of interest, then "ax" and "c" are coefficients (or you could say (ax+c) is the coefficient of y) and (bx+d) is the "constant coefficient."

Your Mileage May Vary

Other sources identify a coefficient as the multiplier of variables. Those sources would ignore any constants or other expressions that don't multiply variables of interest. Check your reference text to see how it defines coefficient.

Comment on your answer choices

You have selected contradictory answers: the numerator term count is 3; the numerator term count is 2. (The denominator term count is 2, but that is not on the list.)

Answer 2

A C

Explanation:

A

A is true.The numerator does have 3 terms. The constant term (the 3 at the end) is still a term and counts as a term.

B

A constant term does not count as a coefficient so b is not right, just as you have indicated by not underlining it.

C

C is true. In fact, 2 is the leading coefficent of the denominator.

D

Either A is true or D is, but I don't think they both are. You need a modifier to claim that D is true. If the statement said the numerator has at least 2 terms then both A and D would be true. Without the at least, you have to pick one and the one I choose is A

E

This is the tough one. Very sticky. You would think it is true, but it isn't. A constant term is not a coefficient. Coefficients only count when they are with "x"s.
