Answer:
y= 2,471x - 230y because each day he travels the same average distance of 230 miles
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:
(1, - 7 )
Step-by-step explanation:
To find a solution, choose any value for x, substitute into the equation and solve for y
Choose x = 1, then
y = - 3(1) - 4 = - 3 - 4 = - 7
Thus (1, - 7 ) is a solution to the equation
Answer:
The conclusion is invalid.
The required diagram is shown below:
Step-by-step explanation:
Consider the provided statement.
If you Sleepwell, you will have extra energy Therefore, if you don't have extra energy. you are not taking Sleepwell.
From the above statement we can concluded that Sleepwell is the subset of extra energy.
If you don't have extra energy that means you can not be in the set of those taking sleepwell
Therefore, the conclusion is valid.
The required diagram is shown below:
A. is obviously the most easiest one, as you just have to fill it up 3 times to get 3 gallons.
The next one to measure exactly 3 gallons of water is B), because:
1) the 100-gallon barrel is more than 1 gallon, and is much more harder than 3 gallons.
2) Each person's 'palm' can hold different amounts of water, and so it can vary by the size of the palm.
So IF it cannot be (A), then your next choice is (B), as you only need 768 teaspoons for each gallon.
But, you should report this problem to the teacher, since A is obviously the best choice
