Answer:

scale factor 1.5 or 1 1/2

Step-by-step explanation:

15/2 is the same as 15÷2 and 15÷2=7.5

now we need to turn 5 into 7.5

to do that lets multiply by 5(1.5) or 5(1+0.5) (the 5 on the outside of the parenthesis means to multiply it by all on the inside)

and we get 5+2.5 or 7.5

so the scale factor is 1.5 or 1 1/2

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

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