Answer:

B. x = -1 or x = 4 1/3.

Step-by-step explanation:

2|3x -5| -8 =8

2|3x -5| = 16

|3x -5| = 8

The expression in the vertical lines can be positive or negative so we have 2 equations:

3x - 5 = 8 and 3x - 5 = -8

3x - 5 = 8

3x = 13

3x - 5 = -8

3x = -8 + 5 = -3

x = -1.

There are 1,000 residents of a town in Year 1. That number increases by 1% each year.

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

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

$y=1,105\ persons$

Guys I really need help plsss

Answer:

x = 3

Step-by-step explanation:

Multiply the first equation by -1, then add it to second equation.

2x+9y = -12

-2x-7y = 8

-------------------

2y = -4

Solve for y

2y = -4

y = -2

Plug value of y into one of the equations and solve for x

2x + 9(-2) = -12

2x = 6

x = 3
