Let n be the number

Twice the number

Plus 5

2n+5

is means equals

2n+5 =3

Now we want to solve

Subtract 5 from each side

2n+5-5 = 3-5

2n = -2

Divide each side by 2

2n/2 = -2/2

n = -1

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).

DanielleElmas [232]

$\bf \begin{cases}
f(x)=\cfrac{8}{x}+4\\\\
g(x)=x^2
\end{cases}\qquad f(\ g(x)\ )=\cfrac{8}{\underline{g(x)}}+4\implies f(\ g(x)\ )=\cfrac{8}{\underline{x^2}}+4$

Identify the terms of the coefficients of the expression. 8x-20y-10

baherus [9]

The terms of this expression would be 8x,-20y, and -10. The coefficients are the numbers in front of the variable so they would be 8 and 20 because they are accompanied by a variable.
