Answer:

The correct option is C) –x + xy – 7y.

Step-by-step explanation:

Consider the provided expression.

Rearrange the expression so, that like terms comes together.

–3x + 2x + 2xy – xy + 4y – 11y

Now, add the like terms as shown below:

x(–3 + 2) + xy(2 – 1) + y(4 – 11)

Now, perform the operation inside the parentheses.

x(–1) + xy(1) + y(–7)

Open the parentheses.

–x + xy –7y

Now, compare with the provided options.

By comparison it can be concluded that the correct option is C).

Hence, the correct option is C) –x + xy – 7y.

Suppose that the functions p and q are defined as follows.p(x) = -2x + 1q(x)=-x?Find the following.
MariettaO [177]

First let us find

(q\mathrm{}p)(x)\begin{gathered} q(p(x))=q(-2x+1) \\ =-(-2x+1)^2 \\ So\text{ } \\ (q\mathrm{}p)(5)=-(-2\times5+1)^2 \\ =-(9)^2 \\ =-81 \end{gathered}

Now let;s solve the second part

\begin{gathered} (p\mathrm{}q)(x)=p(q(x)) \\ =p(-x^2) \\ =-2(-x^2)+1 \\ =2x^2+1 \\ So\text{ (p.q)(5) will be } \\ (p\mathrm{}q)(5)=2(5)^2+1 \\ =51 \end{gathered}
