erica [24]

Answer:

$8,775

Step-by-step explanation:

The amount due is given by the formula ...

A = P(1 +rt)

where P is the principal amount, r is the annual rate, and t is the number of years.

A = $6,500(1 +0.07×5) = $6,500(1.35) = $8,775

Montrey had to pay back $8,775.

Combine the terms in the given polynomial then evaluate for x=3, and y=-1

Novay_Z [31]

Answer: $xy^2+3x^2y;\text{ -24}$

Explanation:

The given expression is:

$xy+3xy^2-2xy+3x^2y-2xy^2+xy$

Combine like terms

$xy+xy-2xy+3xy^2-2xy^2+3x^2y$

Simplify the resulting expression

$\begin{gathered} 2xy-2xy+3xy^2-2xy^2+3x^2y \\ \\ xy^2+3x^2y \end{gathered}$

Substitute x = 3 and y = -1 into the simplified expression

$\begin{gathered} xy^2+3x^2y \\ \\ 3(-1)^2+3(3)^2(-1) \\ \\ 3(1)+(-27) \\ \\ 3-27 \\ \\ =-24 \end{gathered}$
