Answer:
f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:
To find inverse of a function , replace f(t) with y
replace t with y and y with x
solve for y
divide both sides by 100
take ln on both sides
divide both sides by ln
multiply by 3 on both sides
Replace x with t and y with f^-1
f^-1 represents the number of hours the bacteria developed
To find this we can do 2/6 divided by 1/9.
the answer will be 3.
Answer:

Step-by-step explanation:
y=4x+ 1
Answer:
A: [2(200-x)]/3 B: 31.33333...
Step-by-step explanation:
A: Algebraic expression:
Let's say average = x
So the expression is [2(200-x)]/3
You have to take average away from 200, which is 200-x, you have to multiply that whole expression by 2, and then divide everything by 3.
B: Plug in 153 for x:
2(200-153)/3 and then just solve algebraically
=2(47)/3
=94/3
=31.33333...
Answer:
You cannot solve by factoring
Step-by-step explanation:
We want to solve 
by factoring.
We can rewrite as: 
So we have a quadratic equation in 
.
We split the middle term to get:
We look for factors -28 that sum up to -6
This is not possible hence the given equation is not factorable
