Answer:

n=-6

Step-by-step explanation:

distribute -7 into (4n+8)

-10n+50=-28n-56-2

combine like terms

-10n+50=-28n-58

add -28n on both sides

-10n+28n+50=-58

combine like terms again

18n+50=-58

subtract 50 on both sides

18n=-108

divide both sides by 18

$\frac{18x}{18} =\frac{-108}{18}$

x=-6

hope this helps

The graph of f(x) is obtained by reflecting the graph of g(x)=3|x| over the x-axis.

Answer:

Choice B), $f(x) = -3|x|$ .

Step-by-step explanation:

Each point on the graph of $g(x)$ can be represented as $(x, g(x))$ .

When the graph of $g(x)$ is reflected over the x-axis, each point on the graph is also reflected over the x-axis. The x-coordinate of each point will not change but the sign in front of the y-coordinate will flip. For example, $1$ (same as $+1$ ) will become $-1$ , and vice versa. In general, $(x, g(x))$ will become $(x, -g(x))$ .

On the other hand, points on the graph of $f(x)$ can be represented as $(x, f(x))$ . $f(x)$ is the reflection of $g(x)$ , so $(x, -g(x))$ and $(x, f(x))$ shall be equivalent. In other words,
