Answer:

x = -1

Step-by-step explanation:

15+3x=3(2−2x)

Distribute

15+3x = 6 -6x

Add 6x to each side

15+3x+6x = 6-6x+6x

15+9x = 6

Subtract 15 from each side

15-15+9x = 6-15

9x = -9

Divide by 9

9x/9 = -9/9

x = -1

S_A_V [24]

Answer:

Part A) $y=1,000(1.01^{x})$

Part B) $1,105\ persons$

Step-by-step explanation:

Part A) What is the explicit rule for the number of residents

we know that

In this problem we have a exponential function of the form

$y=a(b^{x})$

where

a is the initial value

b is the base

r is the rate

(1+r)=b

Let

y ----> the number of residents

x is the time in years

we have

a=1,000 residents

r=1%=0.01

b=(1+0.01)=1.01

substitute

$y=1,000(1.01^{x})$

Part B) How many residents will there be in the town in Year 10?

For x=10 years

substitute in the equation

$y=1,000(1.01^{10})$

$y=1,105\ persons$
