<span>I will discuss polynomials. A polynomial can be
classified according to the number of expressions that it has in a given
equation. A monomial has only one expression having a coefficient (number) and
a variable (letter). A binomial has two expressions, same as the definition of
the monomial. And a trinomial has three expressions, same as the definition of
a monomial. We can determine the degree of a polynomial by looking at the
exponents of the given polynomial. If an expression has two variables with
different exponents, you can add their exponent to determine their degree.

Answer:
The interest rate is 20%.
Step-by-step explanation:
In order to calculate the interest rate, we need to compute how many percents the value he recieves is related to the total he invested. In this case he recieves 40 every year and he invested 200, to calculate that we will apply a rule of three. We have:
$200 -> 100%
$40 -> x%
200/40 = 100/x
200*x = 40*100
200*x = 4000
x = 4000/200 = 20
The interest rate is 20%.
Because there is no whole number that you can divide into both the numerator and the denominator to get a proper fraction.
Answer:
X=-1/3 y-2
Step-by-step explanation:
Let's solve for x.
y
=

$3,650, because $32,000+$5500=$37,500 Then you do $37,500 minus $33,850=$3,650
