Following are the function description to the given question:
Step-by-step explanation:
In the given-question, three functions are used, that can be defined as follows:
In function 1:
This function is also known as the modulus on the absolute value function, for example:

In the given in the above graph, that is 
In function 2:
In this function, It is an algebraic function that is 
It is also a part of the quadratic polynomial function, and its value is
In function 3:
In this function, it is the cubic polynomial equation that's value is 
In the graph its value is:
Answer:
x=19
Step-by-step explanation:
These two angles are alternate interior angles and alternate interior angles are equal when the lines are parallel
148 = 7x+15
Subtract 15 from each side
148-15 =7x+15-15
133 = 7x
Divide by 7
133/7 = 7x/7
19 =x
