The correct answer is A. rational expression

Rational expression refers to a fraction in which the numerator and denominator are polynomials. Polynomials are variables. So therefore rational expression is the answer to the term that describes a fraction that has a variable or variables expression in its numerator and it denominator or both.

Answer: the term described a fraction that has a variable or variable expression in its numerator is called the rational number

Explanation:

Rational number is basically the quotient of two integers and the denominator is not zero (remember that you can never divide by zero; if you do the answer always will be infinity)  

For example:

1 divided by 3 = 1/3 is a rational number

-5 divided by 8 = -5/8 is also a rational number

Alex Ar [27]

Answer:

  • 3/68

Step-by-step explanation:

<u>Given</u>

  • Total 17 marbles
  • 4 - blue marbles
  • 6 - green marbles
  • 2 - red marbles
  • The rest - yellow marbles

<u>Probability of drawing red first:</u>

  • P(red) = number of red / total number = 2/17

<u>Probability of drawing green second, without replacement:</u>

  • P(green) = number of green / number left in the bag = 6/16 = 3/8

<u>Probability of red and green in order:</u>

  • P = P(red)*P(green) = 2/17*3/8 = 3/68

When x=-2 and y=-1,-x^2-5xy+5y^3 is
kirill115 [55]

Answer:

-19

Step-by-step explanation:

Evaluate -x^2 - 5 x y + 5 y^3 where x = -2 and y = -1:

-x^2 - 5 x y + 5 y^3 = -(-2)^2 - -2 (-5) + (-1)^3×5

(-2)^2 = 4:

-4 - -5 (-2) + 5×(-1)^3

(-1)^3 = -1:

-4 - -5 (-2) + 5×-1

-5 (-2) = 10:

-4 - 10 - 5

-4 - 10 - 5 = -(4 + 10 + 5):

-(4 + 10 + 5)
