Answer:

original fraction =12/5

Step-by-step explanation:

let x = numerator

therefore

   x+3/x-7+3 =15/8

    x+3/x-4 =15/8

      8(x+3)=15(x-4)

      8x+24=15x-60

       84=7x

        84/7=x

        12=x

therefore original fraction = 12/5

(x – 4)2 = -9 has no real solution
Keith_Richards [23]

Answer:

x = -1/2

Step-by-step explanation:

(x - 4) * 2 = -9

Divide both sides by 2:

x - 4 = - 9 / 2

Add 4 to both sides:

x = - 1 / 2.

The population of a city can be modeled by P(t) 3810(1.0005)7t , where P(t) is the population after t years. Which function is a
swat32

Answer:

P(t) = 3810(1.0035)^{t}

Step-by-step explanation:

Given:

P(t) = 3810(1.0005)^{7t}             -----(1)

Simplifying (1.0005)^{7t}

From Law of indices, x^{mn} = (x^{m})^{n}

(1.0005)^{7t} = (1.0005^{7})^{t}

When 1.0005 is raised to the 7th power, it is approximately 1.0035.

Substituting (1.0005)^{7t} = (1.0035)^{t} into equation(1)

P(t) = 3810(1.0035)^{t}
