Answer:

Step-by-step explanation:
Steps to find the inverse function:
1) replace f(x) with "y"

2) solve for x:

3) replace "x" with
, and y with x:

Answer:
x=-20
Step-by-step explanation:
x-3/4x=3/10x-1
20x-15x=6x+20
5x=6x+20
5x-6x=20
-x=20
x=-20
Basically here all you want to do it substitute the values x=1 and x=2 for the given function. Use your slope formula
.
Do same for x=3 and x=4
You next divide plug in values in to this expression:

To solve this formula for T it is the last one.
T = Q divided by the quantity M times C.
Answer:
Quadratic equation follows form: ax^2 + bx + c = 0
a = 8
b = - 6
c = 13
