Nadia built a robot to filter air and water efficiently. She expects the robot to filter more than 343 liters of air and water w
chubhunter [2.5K]

12A+8W > 343 represents the number of minutes the robot filters air A and water W to filter more than 343 liters of air and water.

If the robot filters air for 20 minutes and water for 15 minutes, plugging A as 20 and W as 15, let us check if the equation is true or not.

Checking left side:

12A + 8W = 12(20) +8(15)

240+ 120 = 360

Checking right side: 343

12A+8W > 343

360>343

True.

So the robot meets the first expectation.

Let us check for second equation:

3A+4W < 49

Left side : 3A +4W = 3(20) +4(15) = 60 +60 =120

Right side is 49

comparing left and right side:

3A+4W < 49

120<49

False.

So the robot does not meet the second expectation.

Ahat [919]

Answer: d. The domain would only include positive numbers.

Step-by-step explanation:

Given: A function is created to represent the miles per gallon your car gets.

Here, the independent variable = the amount of fuel the car gets in gallons.

and the dependent variable = the total miles of car travel .

We know that the domain of a function is a set of all values of independent variable.

Thus, the domain would only include positive numbers because the quantity of fuel in a car is never negative and it can be in fraction .

Hence, D is the right answer.
