Answer:

<u>2,048 cells</u>

Step-by-step explanation:

Number of cells after 1 hour = 4 * 2 = 8

Number of cells after 2 hours = 8 * 2 = 16

Number of cells after 3 hours = 16 * 2 = 32

Number of cells after 4 hours = 32 * 2 = 64

Number of cells after 5 hours = 64 * 2 = 128

Number of cells after 6 hours = 128 * 2 = 256

Number of cells after 7 hours = 256 * 2 = 512

Number of cells after 8 hours = 512 * 2 = 1,024

Number of cells after 9 hours = 1,024 * 2 = 2,048

1. Write an equation in point-slope form for the line through the given point with the given slope.
ElenaW [278]

Answer: y + 2 = \frac{-1}{2} ( x - 4 )

Step-by-step explanation:

The equation of a line in point - slope form is given as ;

y - y_{1} = m (x -  x_{1})

x_{1} = 4

y_{1} = -2

m = \frac{-1}{2}

Substitute the values into the equation , we have

y - (-2) = \frac{-1}{2}( x - 4 )

y + 2 = \frac{-1}{2} ( x - 4 )

Which could be written as :

y + 2 = y + 2 = \frac{-1}{2} x + 2

2<br> — x = 6<br> 3<br><br> Any help? Please?
Mama L [17]
X = 9
you multiply both sides by 3 because you have to get rid of it and what you do to one side you do to the other then you divide both sides by 2 to isolate the variable. i hope that makes sense.
