An epidemic has hit clinton city. its population is declining 22% every hour. in just 4 hours, there are only 35,542 people left in the city. what was the initial population in the city before the epidemic broke out? 85,689 14,742 85,688 14,743

Step-by-step explanation:

Clinton city was hit by an epidemic and hence population was declining 22% every hour

Let t be the no of hours after epidemic and A, the initial population at the start of epidemic

Then

Also given that P(4) = 35542

We have to calculate A from this

Substitute t =4 and P (4) = 35542

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
