According to the 2000 Census the population of Canton was 7,720. Holly Spring's population was 3,200. Canton's population increa
Kazeer [188]
Firstly, the rate of increase of Canton = 80/7720 = 0.010
The rate of increase of HP = 120/3200 = 0.0375
Apply  the formula of compound interest==> A =A'(1+i)^n
The population will be equal when the following equality is satisfied

7720(1+0.01)^n = 3200(1+0.0375)^n

or

7720x1.01^n = 3200x1.0375^n

Divide both sides by 3200 ===>(193/80)x1.01^n=1.0375^n

8x + y = 9 <br> Convert the following equations to standard form
Citrus2011 [14]

Answer:

x=1/8y+9/8    

y=<u>y=−8x+9</u>

Step-by-step explanation:

<u>Let's solve for y.</u>

<u>8x+y=9</u>

<u>Step 1: Add -8x to both sides.</u>

<u>8x+y+−8x=9+−8x</u>

<u>y=−8x+9</u>

<u />

<u>Let's solve for x.</u>

<u>8x+y=9</u>

<u>Step 1: Add -y to both sides.</u>

<u>8x+y+−y=9+−y</u>

<u>8x=−y+9</u>

<u>Step 2: Divide both sides by 8.</u>

<u>8x/8=−y+9/8</u>

<u>x=−1/8y+9/8</u>
