We know that:
∠ABC=∠BCA=xº
∠BDC=∠BCD=xº
1) we have to find the angle ∠DBC:
∠BDC+∠BCD+∠DBC=180º
xº+xº+∠DBC=180º
2xº+∠DBC=180º
∠DBC=180º-2xº
2) we have to find the angle ∠ABD:
∠ABD=∠ABC-∠DBC
∠ABD=xº-(180º-2x)
∠ABD=xº-180º+2xº
∠ABD=3xº-180º
Answer: ∠ABD=3xº-180º
Ashley starts with 45 comics.
So in the first box:
x = 0, y = 45
-------------------------------------------------------------------------------------------------------
Each month, she adds 5 comic books to her collection
x (+1), y (+5) (for each month).
First month.
x = 0
y = 45
Second month
x = 1
y = 45 (+5) = 50
Third month
x = 2
y = 50 (+5) = 55
etc.
-------------------------------------------------------------------------------------------------------
B) is your best choice, as for every month add (+1), the comic books increase by 5 respectively.

Answer:
B
Step-by-step explanation:
The domain is the set of x values for which the function is defined.
The range is the set of y values for which the function is defined.
Attached is the graph of the exponential function.
It is the basic graph of exponential function of y = 5^x which is shifted 6 units above (because of +6 at the end).
<em><u>Looking at the graph, the domain is the set of all x values.</u></em>
<em><u>The range is anything above 6.</u></em>
Correct answer is B.
