Answer:

Step-by-step explanation:
Given data
Number of balls= 480
we are told that 50%(half) of the balls are put back every 1
let the number of hours be x
and let the remaining ball be y after x hours
Hence the expression is given as

Answer:
it a 90 degree angle hope this helps:)
Step-by-step explanation:
Answer:
Infected = itself + itself
Healthy = 200 - infected
y axis = weeks
x axis = # of people
use green for healthy and red for infected
and mark going by weeks
green:
(1, 199)
(2, 198)
(3, 196)
(4, 192)
(5, 184)
(6, 168)
(7, 136)
(8, 72)
(9, -56)
red:
(1, 1)
(2, 2)
(3, 4)
(4, 8)
(5, 16)
(6, 32)
(7, 64)
(8, 128)
(9, 256)
(10, 512)
The slope of a line is rise over run, which is the change in y over the change in x. Here, the change in y over the change in x would simplify to (3-2)/(2-4). It does not matter what point you choose to put as the first value, but if you put that point as the first value for x, you have to do the same for y. This equation simplifies to our answer of a slope of 1/2 or 0.5
