X + x + x + 20 + 10 = 180
(combine like terms)
3x + 30 = 180
3x=180-30
3x=150
x=150/3
x=50

Answer:

x°=50°

Step-by-step explanation:

x°+(x+10)°+(x+20)°=180°
3x+30=180°
3x=180_30
3x=150
finally divide both side by 3
x= 50.

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

Alinara [238K]

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,
