I was super busy today, and didn't have time to finish my math homework. I really hope you guys can help me, as I need the point
s for this. All you need to do is to simplify the expressions shown. I already have the answers, I just need to know how to show my work. If it helps, the answers are: 11) 50/3 - 35/12n
12) -19.58x + 18.48
13) 13/20 - 10/7v
14) -23/20 + 13/30x
And any explanations would be very helpful, as it would help me a lot in the future.

Step-by-step explanation:
The linear function
One of the points is (0,5), so
f(0) = 5
The y-intercept is at (0,5).
===============
The exponential function
The general formula for an exponential function is .
=====
Calculate the <em>value of b </em>
y₃/y₂ = [a(b)³]/[a(b)²]
250/50 = b
b = 5
=====
Calculate the <em>value of a </em>
250 = a(5)³
250 = a × 125
a = 2
=====
g(0) = 2(5)⁰
g(0) = 2 × 1
g(0) = 2
=====
|f(0) – g(0)| = |5 – 2|
|f(0) – g(0)| = 3
The positive difference in the y-intercepts of f(x) and g(x) is 3.
You can see the two y-intercepts on the graph below.
