zheka24 [161]

Answer:

263,606.9

Step-by-step explanation:

In 2004 the population in Morganton, Georgia, was 43,000.

(0, 43000)

The population in Morganton doubled by 2010

In 6 years the population is doubled (86000)

(6,86000)

A= a(b)^t

Use (0,43000) in the above equation

A= a(b)^t\\43000= a(b)^0\\a=43000

Now plug in (6,86000)

A= a(b)^t\\A= 43000(b)^t\\86000=43000(b)^6\\2=b^6\\b=\sqrt[6]{2} \\b=1.12

A=43000(1.12)^t

Now find out A when t=16 (2020)

A=43000(1.12)^t\\A=43000(1.12)^{16}\\A=263606.9

Which ordered pair in the form(x,y) is a solution of this equation?
Gnom [1K]

The ordered pair is (-2, -3)

Step-by-step explanation:

  • Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.

(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1

(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1

(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1

(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1

So the ordered pair is (-2, -3)

Can someone help me with this math homework please!
kobusy [5.1K]

Answer:

It's 2, 1, and y = 2x + 1.

Step-by-step explanation:

You can see the rise is 2 and the run is 1, making the slope = 2, and the y-intercept is 1 because that is where it crosses the y axis. Once you have the slope and y intercept, you can put it in a function, with the form being y=2x+1, the slope being the number before the x and the y-int value being after the x.
