Greg has nickels and pennies in his pocket. the number of pennies is three less than twice the number of nickels. let n represent the number of nickels

The expression for the number of pennies Greg has is 2 × n - 3

The reason the above expression is correct is as follows;

Question: The part of the question that appears missing is to; Write an expression for the number of pennies

The given parameters are;

The denominations of currency Greg has in his pocket = Nickels and pennies

The number of pennies he has = 2 × The number of nickels he has  - 3

The number of nickels = n

Therefore, by plugging in the variable for the number of nickels, we have;

The expression for number of pennies = 2 × n - 3

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
