Answer:
45.5
Step-by-step explanation:
Use pyth theorem to find the whole bottom side. Then sub 16 by 13. # is the small segmented area. The small segmented tri is 10.5 area. The big tri is 56. Sub 10.5 from 56 to get 45.5.
Answer:

Step-by-step explanation:
First, subtract by 7 both sides of equation.

Solve.


Then, divide by 12 both sides of equation.

Solve to find the answer.

, which is our answer.
Answer:
(-4,1)
Step-by-step explanation:
The answer is just where the two lines intersect
I'm rather tired so double check me on this but I'm getting about (-4,1) and it's asking for an approximation so think (-4,1) is fine
Answer: Choice C. 
============================================
Explanation:
The domain is the set of all allowed x inputs.
Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.
We can say the domain is
which can be simplified to
or 
In short: x can be -3 or larger.
