Step-by-step explanation:
It is given in the question that
A prom ticket at Valley high school cost $160. Bryan is going to save money for his ticket by walking his neighbor’s dog for $21 per week. Bryan has already has saved $35.
Let the number of weeks be x
And sum of saved money and his earning in x weeks must be greater than or equal to 160.
That is
The parent function of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)
<h3>What are parent functions?</h3>
Parent functions are the basic function that represents the entire family of that function family
<h3>How to determine the parent function?</h3>
The function is given as;
g(x) = 3cos (x + 180°) + 1
As a general rule, the parent function of any function is the basic equation of the function family
The basic equation of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)
Hence, the parent function of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)

There are a lot of ways to do it such as:
10/12x+4/6=-9
10/12x=-50/6
10/12x=-25/3. Hope it help!
