Answer:
i) y∝x => y = kx and k = 2.5
ii) When x = 7, y is 17.5
Step-by-step explanation:
If y is directly proportional to x then according to the question
y∝x which means y =kx where k is any constant
From the above example
8y=20x comparing it with y = kx
y = (20/8)x
y = 2.5x
Here k = 2.5
i) y∝x => y =2.5x
ii) if x=7 then y = ?
From above
y=2.5x
Put x = 7
y = 2.5 x 7
y = 17.5

Step-by-step explanation:
Answer: that is the most it can be simplified
Step-by-step explanation:
there are no like terms to combine.
The formula for this question is P(n) = P*(1+r)^n
So the initial population is 8600 or P, and n can be the number of years. r is the rate it grows, 3% or 0.03.
Plug in these values
P = 8600
r = 0.03
n = 3
into P(n) = P*(1+r)^n
