For the diagrams, find the following measures. X= DCB= ABC=

Tasya [4]

To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180.
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157

X= 23

Hope this helped :)

Answer: true

Step-by-step explanation:

But it isn't a linear functionA function with a constant rate of change and a straight line graph., because it doesn't follow a straight line. Any function that isn't linear is called a nonlinear function.

Let f(x)=3x^2+5 . The quadratic function g(x) is f(x) translated 3 units up. Enter the equation for g(x) in the box. g(x) =

Phantasy [73]

Answer: $g(x)=3x^2+8$

Step-by-step explanation:

There are some transformations for a function $f(x)$ . Two of those transformations are:

1. If $f(x)+k$ , then the function is translated "k" units up.

2. If $f(x)-k$ , then the function is translated "k" units down.

In this case, you have the following Quadratic function $f(x)$ given in the exercise:

$f(x)=3x^2+5$

According to the information given, the function $g(x)$ is obtained by translating the Quadratic function $f(x)$ 3 units up. Based on this, you can identify that the transformation is the following:
