<u><em>The complete question is</em></u>
Jaden and Joel both worked at the coffee shop today. Jaden's total cups of coffee made is represented by f(x), and Joel's total cups of coffee made is represented by g(x). Use the functions below to write a function that represents the total cups of coffee they made today.
f(x) = 4x − 1
g(x) = 2x + 3
Options
6x + 2
2x + 1
2x − 4
4x + 4
we know that
To find out the total cups of coffee they made today, sum Jaden's total cups of coffee plus Joe's total cups of coffee
so
f(x)+g(x)
substitute the values

Answer:
Part 19) x=5
Part 20) x=-3
Step-by-step explanation:
Problem 19) Find the value of x so that f(x)=7
step 1
Find the intersection point of the given line in the graph with the line y=7
The intersection point is (5,7)
see the attached figure
therefore
The x-coordinate of the intersection point is the value of x when f(x)=7
x=5
f(5)=7
Problem 20) Find the value of x so that f(x)=7
step 1
Find the intersection point of the given line in the graph with the line y=7
The intersection point is (-3,7)
see the attached figure
therefore
The x-coordinate of the intersection point is the value of x when f(x)=7
x=-3
f(-3)=7
