Approximately 84 people will be sick with the flu after 11 days. The equation is f(x)=36(1.08)^x and you would substitute the amount of days in for x. The formula I used is f(x)=ab^x where a is the initial value and b is the multiplicative rate of change.
No there is no variability cause the answers will always be the same
Answer:
x=-1 y=2
Step-by-step explanation:
Use Elimination or Substitution (Elimination shown below)
6x+5y=4
6x-7y =-20 <- Multiply by -1
-6x+7y=20
12y = 24
y=2
Plug back into either of the equations and solve for x.
6x + 10= 4
6x = -6
x = -1
Double check work:
-6+10 = 4
