to the left side of the equation.

Subtract x

from both sides of the equation.

2x−3−x=0

Subtract x

from 2x

x−3=0

Add 3

to both sides of the equation.

x=3

A bacteria culture begins with 15 bacteria which double in amount at the end of every hour. How many bacteria are grown during t
elixir [45]
We use P = i•e^rt for exponential population growth, where P = end population, i = initial population, r = rate, and t = time
P = 2•i = 2•15 = 30, so 30 = 15 [e^(r•1)],
or 30/15 = 2 = e^(r)
ln 2 = ln (e^r)
.693 = r•(ln e), ln e = 1, so r = .693
Now that we have our doubling rate of .693, we can use that r and our t as the 12th hour is t=11, because there are 11 more hours at the end of that first hour
So our initial population is again 15, and P = i•e^rt
P = 15•e^(.693×11) = 15•e^(7.624)
P = 15•2046.94 = 30,704

HELP PLEASE!! WILL GIVE BRAINLIEST!!!
beks73 [17]

Answer:

Slope = 2 Y-Intercept = (0, 3)

Step-by-step explanation:

Slope : \frac{Rise}{Run}  which is \frac{y2 - y1}{x2 - x1} from two points: point1 (x1 , y1) and point2 (x2, y2).

For the purpose of getting the slope I will be using point (0, 3) as point 1

and point (-3, -3) as point 2.

If you plug in 0 as x1, 3 as y2, -3 for x2, and -3 for y2:

\frac{-3 - 3}{-3 - 0} = \frac{-6}{-3} = 2

Y-Intercept: The y intercept is the point where the line is touching the y axis. Which in this graph, there is only point (0,3).
