We know that C is dependent on how many hours of service was done. We also know that C is linearly dependent on how many hours of service was done because it's a constant $50 per hour.
So, the equation would be a linear equation in the form C = 50h + L where h is the number of hours and L is the y-intercept.
Since there is an initial charge of $25, when h = 0, C = $25 -> L = $25.
So, the equation is C = 50h + 25.

Step-by-step explanation:
Answer:
5.7a - 18.2b
Step-by-step explanation:
<u>Step 1: Write the equation</u>
(12.2a + 9.7b) – (18.1b – 0.2a) – (6.7a + 6.8b)
<u>Step 2: Open all brackets</u>
12.2a + 9.7b - 18.1b + 0.2a - 6.7a - 6.8b
<u>Step 3: Arrange all 'a' together and all 'b' together</u>
12.2a + 0.2a - 6.7a + 9.7b - 18.1b - 6.8b
<u>Step 4: Simplify</u>
5.7a - 18.2b

Yeah i could be your friend lol
What it's asking is to put the equation in either f(x) or g(x).
so for
(a) you would replace all x in f(x) equation with g(x) equation.
f(x) = 3x - 2
f(g(x)) = 3(5x + 4) - 2
solve from there
(b) g(x) = 5x + 4
g(f(x)) = 5(3x - 2) + 4
