Answer:
see below
Step-by-step explanation:
Setting x=0, you can find the y-intercept:
y = 4
Setting y = 0, you can find the x-intercept:
2x = 4
x = 2
The boundary line can be drawn through these intercept points, (0,4) and (2,0). Because the "equal to" case is not included, the boundary line will be dashed.
The y variable is on the open side of the comparison symbol (y>), so the shading is above the boundary line. That is where y-values are greater than those on the line.

A 6 sided figure’s angles are going to add up to 720 degrees. First, to find the value of x, you add up all of the angles.. 110 + 150 + 115 + 130 + 115 = 620. Next, you subtract 620 from 720 to get 100. Since that angle is equal to 2x, we now know that 2x = 100. Next, we dived 100 by 2 to get 50. So, the value of x = 50.
To find the value of y, we know that a straight line is equal to 180 degrees. Y and 130 degrees are supplementary angles. So, we subtract 130 from 180 to get 50 degrees. So, the value of y = 50
Answer:
Option B
![g(x) = -6x^2](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-6x%5E2)
Step-by-step explanation:
If the graph of the function
represents the transformations made to the graph of
then, by definition:
If
then the graph is compressed vertically by a factor c.
If
then the graph is stretched vertically by a factor c
If
then the graph is reflected on the x axis.
In this problem we have the function
We now that this function is vertically stretched by a factor of 6 to g(x) and reflected over the x-axis
Then
and ![c=-6](https://tex.z-dn.net/?f=c%3D-6%3C0)
Therefore the graph of
is ![g(x) = -6f(x)](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-6f%28x%29)
![g(x) = -6x^2](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-6x%5E2)
