We have to find the value of the expression 
We know that the below values.

Hence, in order to find the value of the given expression, we can first rewrite it in terms of 

Now, we know that 
Hence, we have



C is the correct option.
Answer:
False
Step-by-step explanation:
The open circle means you should not include the number it is on.
The inequality would look like, x<2 and not equal to. Therefore, 2 is not a solution.
Answer:
The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.The vertical change between two points is called the rise, and the horizontal change is called the run.
Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:

Plug in the values



Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
Hello there! 9+7=16. I hope this helps!
