A. x-6=6
if u plug in 12, you get 12-6=6 which is true
all the other ones would be false if you plugged in 12
Using a linear function, it is found that the rate of change in this problem situation is of -2 contestants per week.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the situation described, the number of participants after n weeks is given by:
N(n) = 20 - 2n.
The slope is of -2, hence the rate of change in this problem situation is of -2 contestants per week.

Answer:
9/20
Step-by-step explanation:
First you'd do 3/5 x 3/4 because the denominators aren't the same. When you multiply them you get 9/20. That's your answer! If your not satisfied look it up on Google lol.
Answer:
Option A. 14.13 cu. in
The volume of the water balloon is 14.13 in³
Step-by-step explanation:
First we calculate the radius
r = 3in / 2
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 1.5in
π = 3.14
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * 3.14 * (1.5in)³
V = 4.187 * 3.375 in³
V = 14.13 in³
The volume of the water balloon is 14.13 in³
