Answer:
y = 259.6/2 = 129.8 degrees. so x = 129.8 - 79.6 = 50.2 degrees.
Step-by-step explanation:
I got this answer from somewhere else. but it is correct. i hope this helped.
This gives you, 4x + 5y = -25 as your final answer.
1.) <1=25°, <2=155°, <4=155°
I think it would be 3 because if you divide 18/6=3
Answer:


Step-by-step explanation:
Given

Solving (a): 
We have:

Express f(x) as y

Swap x and y

Add 8 to 


Square both sides

Rewrite as:

Express y as: 

To determine the domain, we have:
The original function is 
The range of this is: 
The
of the
function is the
of the
function.
<em>Hence, the domain is:</em>
