total cost = 10 * adults + 6 * children
total cost = 10*2 + 6 * 3
total cost = 20 + 18
total cost = 38
We are looking to find the point where the curve discontinued
Step 1: Factorise both numerator and denominator (if possible)
![\frac{x+5}{ x^{2} +3x-10}= \frac{(x+5)}{(x+5)(x-2)}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B5%7D%7B%20x%5E%7B2%7D%20%2B3x-10%7D%3D%20%5Cfrac%7B%28x%2B5%29%7D%7B%28x%2B5%29%28x-2%29%7D%20%20)
Step 2: Recognise the common factor, which is
![(x+5)](https://tex.z-dn.net/?f=%28x%2B5%29)
Step 3: Equate the common factor to 0
![x+5=0](https://tex.z-dn.net/?f=x%2B5%3D0)
![x=-5](https://tex.z-dn.net/?f=x%3D-5)

Answer:
Haha proofs are an interesting thing. Usually, nothing is to scale, which is why you can't measure anything. They are pretty annoying, but it helps to know why certain things are the way that they are and develop justification skills for higher level math.
Sorry to discourage you, but you're going to see "Justify" quite a lot in calculus and beyond which is basically a more informal version of a proof
you can never escape it tbh lol
