Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form: 
....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function: 
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
Your answer would be B. 0.09, the reason being is that any number that has a 0 and then a decimal point is irrational (or a regular fraction

First, let's move combine like terms:
-5y + 8y = 6 + 2 -12.
3y = -4.
y = -4/3
Answer: m²-9mn+2n²
Step-by-step explanation: make use of BODMAS strategy. Let the unknown be x.
-7mn+2m²+3n²-x= m²+2mn+n². Since we are concerned about getting the unknown,let's try to collect the like terms.
-7mn+2m²+3n²-(m²+2mn+n²)= x
-7mn+2m²+3n²-m²-2mn-n²= x
-7mn-2mn+2m²-m²+3n²-n²=x
-9mn+m²+2mn= x
X= m²-9mn+2n²
