Aresearcher is testing how bacterial cells react to different environments. she placed a petri dish that initially had 32,000 bacterial cells in a vacuum chamber. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.
the researcher creates an equation that models this pattern and can be solved to find the number of cells, y, in the dish x hours after being placed in the vacuum chamber. plot the y-intercept of the equation and the points representing the solutions for the first three hours after the cells were placed in the vacuum chamber.

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

step-by-step explanation:

de-gf

hj=3x+20

ji=15x-64

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
