Answer:

Disproved

Step-by-step explanation:

We are given the formula and what both variables equal. So, we can solve to see if this is true.

x = 54 and y = 45

54 + 45 = 11(54 + 45)

99 = 11(99)

99 ≠ 1089

Since they don't equal the same, this disproves it.

Best of Luck!

Step-by-step explanation:

If we use this formula then

X is 54 y is 45

54 + 45 = 11(54 + 45)

99 = 11(99)

99 = 1089

= 1089 - 99

= 990

if a town with a population of 500 doubles in size ever 9 years, what will the population be 36 years from now?
s344n2d4d5 [400]

The population of the town in 36 years would be  8000.

<h3>What would be the population of the town in 36 years?</h3>

The formula that can be used to determine the town's population is:
FV = P (1 + r)^n

Where:

  • FV = Future value
  • P = Present value
  • R = rate of growth = 100%
  • N = number of years = 36/9 = 4

500 x 2^4 = 8000
