Is x^(-2)+5 a polynomial expression? Why or why not? Read More >>

Mathematics
1 answer:
Mariulka [41]3 years ago
4 0

Well.. a polynomial expression is an expression that has 3 or more different algebraic terms.

Algebraic terms can be: x^2, 2x, or x^3

One example is: x^2 + x^3 - 7y

Since x^(-2)+5 only has one algebraic term, which is x^(-2), this is not a polynomial.

Which of the following is an example of direct variation?
LekaFEV [45]

Answer:

C

Step-by-step explanation:

Direct variation is a special case of first order equations; in both cases, the input is multiplied by a constant which we call the "slope" or "constant of variation."  However, no direct variation equation includes a constant ("y-intercept").  So, if a given equation does have a y-intersect, that equation does not represent direct variation; if it does NOT have a y-intercept, that equation represents direct variation.

A)  involves a constant term, -2; NOT direct variation

B)  involves a constant term, 10; NOT direct variation

C)   Here 3y = x, or y = x/3, involves no constant term, so Does represent direct variation

D)  involves a constant term -3; NOT direct variation
