Answer:

The answer to your question is y = -2x + 9

Step-by-step explanation:

A (9, 9)

B (-2, 13)

Process

1.- Find the slope

m = $\frac{y2 - y1}{x2 - x1}$

$m = \frac{13 + 9}{-2 - 9}$

$m = \frac{22}{-11}$

m = - 2

2.- Find the line equation

(y - y1) = m (x - x1)

y + 9 = -2 (x - 9) y + ? = [ ] ( x + [ ])

y + 9 = - 2x + 18

y = - 2x + 18 - 9

y = -2x + 9

Bacteria can multiply at an alarming rate when each bacteria splits into two new cells, thus doubling. If we start with only one

Elan Coil [88]

Answer:

2^24 = 16,777,216 bacterias.

Step-by-step explanation:

So we start with 1 bacteria

after 1 hours: 2*1 = 2

after 2 hours: 2*2 = 2^2 = 4

after 3 hours: 2*2^2 = 2^3

after n hours: 2^n

Since one day has 24 hours we have n = 24 and total number of bacteria will

be: 2^24 = 16,777,216 bacterias.

1. Kyle and John are twins who decided to plan an imaginary trip that started with cliff jumping. There were two different spots

Vikki [24]

Answer:

a) Δx = -35ft

b) Δx = -25ft

c) Kyle traveled 10ft more than John

Step-by-step explanation:

We define a coordinate reference system() in which y = 0 corresponds to the water surface.

a) The initial position of Kyle in our coordinate reference system is:

$x_{o} = 20 ft$

and his final position is:

$x_{f} = -15 ft$

Therefore, he traveled

Δx = $x_{f} - x_{o} = -15 - 20 = -35 ft$

b) The initial position of John in our coordinate reference system is:

$x_{o} = 15 ft$

and his final position is:

$x_{f} = -10 ft$

Therefore, he traveled

Δx = $x_{f} - x_{o} = -10 - 15 = -25 ft$

c) Then, Kyle traveled 10ft more than John
