Because angleCBD＋angleBDC＋angleC＝180
so angleCBD＋angleBDC＝180－angleC＝180－82＝98
because BC＝DC
so angleCBD＝angleBDC
so 2 angleCDB＝98
so angleCDB＝49
so y＝29

Answer:
y = 1/2x -2
Step-by-step explanation:
The slope of the equation is over 1 and to the right by 2 so Rise/run = 1/2
The y-intercept is -2
Answer:
A math teacher
Step-by-step explanation:
Basically you just divide:
123/3 = 41
So the sale price of the coat would be $41
R(x) is a polynomial. Thus, the domain is the same as the range.
Domain = range = ALL REAL NUMBERS.
We can also express the answer as
(-infinity, infinity).
