Which polynomials are in standard form?

Mathematics
1 answer:
pickupchik [31]3 years ago
3 0

Answer:

A and C are the correct answers.

Step-by-step explanation:

Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.

  • In choice A, since 3z has a variable, it goes before 1.
  • In choice C, since -5p^5 has the highest exponent it does go first.
  • Then 2p^2, since it has the second highest exponent.
  • Then -3p follows, with the lower exponent.
  • Then 1 goes last because it has no variable and has the lowest exponent.

s2008m [1.1K]

Answer:

\displaystyle \text{Function: }{y=20-3x,\\\text{Domain: }(-\infty, \infty)\text{ or }\mathbb{R}

Step-by-step explanation:

If the boy initially had 20 cents, then the total number of cents he will have left after purchasing x pencils is equal to the total cost of the pencils subtracted from 20. The total cost of x pencils, in cents, is equal to 3x, since each pencil is 3 cents.

Therefore, the total amount, in cents, that the boy has left, y, is equal to 20-3x:

\displaystyle \text{Equation: }\boxed{y=20-3x}

The domain of this function is (-\infty, \infty) or all real numbers \mathbb{R}.
