Answer:

Step-by-step explanation:
The <u><em>Triangle external angle theorem</em></u> states that :An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see
see the attached figure with letter to better understand the problem
step 1
Find the measure of the interior angle at B
we know that
----> by supplementary angles (form a linear pair)

step 2
Find the value of x
Applying the triangle external angle theorem

solve for x



simplify

Answer: y=-x +2
Step-by-step explanation:
1y=-x+2
1y/1=-x/1+2/1
y=-x+2
Answer:
7.65 meters.
Step-by-step explanation:
Let x represent the distance that diver will travel.
We have been given that a scuba diver is exploring at an elevation of -12.2 meters. As the diver rises to the surface, she plans to stop and rest briefly at a reef that has an elevation of -4.55 meters. We are asked to find the distance that diver will travel.
The initial elevation plus x will be equal to -4.55 meters. We can represent our given information in an equation as:



Therefore, the scuba diver will travel a vertical distance of 7.65 meters.
Answer:
The answer is "It has the same domain as the function f(x) = --x".
Step-by-step explanation:
If we consider its parent function that is: y= x
Domain function is:
The range function is: 
The function has both the same (domain and range).
