Fernando built a robot to filter air and water efficiently. He expects the robot to filter more than 512 liters
of air and water while using less than 9 Joules of energy.
A represents the number of minutes the robot filters air, and W represents the number of minutes the
robot filters water.
21A + 14W > 512 represents the number of minutes the robot filters air and water to filter more than
512 liters of air and water.
0.36 A + 0.6W < 9 represents the number of minutes the robot filters air and water while using less
than 9 Joules of energy.
Does the robot meet both of Fernando's expectations by filtering air for 15 minutes and filtering water for
5 minutes?

Answer:

x= -33/2 or x=-16.5

Step-by-step explanation:

Expand the bracket

6(2x+3) = 2(5x-3)

12x+18=10x-15

Bring like terms together

12x-10x=-15-18

2x=-33

x=-33/2

Answer: the small number: 2

Answer:

y = 3x

Step-by-step explanation:

To find out what the equation is here, divide the y coordinate by the x coordinate of the point given (2, 6). Here divide 6 by 2. That would equal 3. That means that the y coordinate is 3 times as much as the x coordinate. As a result we can make the equation y = 3x out of what we now know.

Answer:

Step-by-step explanation:

In this question we will solve the polynomials by adding or subtracting the similar terms.

1). (-3x² - 8x + 2) + (-5x² - 9x - 2)

   = (-3x²- 5x²) - (8x + 9x) + (2 - 2)

   = (-8x²) - 17x + 0

   = -8x² - 17x

2). (-2x² + 7x - 1) - (8x² - 6x + 5)

   = (-2x² - 8x²) + (7x + 6x) - (1 + 5)

   = -10x² + 13x - 6

3). (5x²- 5xy - 10y²) + (5x²+ 5xy + 10y²)

   = (5x² + 5x²) + (-5xy + 5xy) + (-10y² + 10y²)

   = 10x²

4). (2 + 8x + 4x²) - (9 + 6x + 2x²)

   = (2 - 9) + (8x - 6x) + (4x² - 2x²)

   = -7 + 2x + 2x²

5). (4x³ + 5x²+ 3x) - (3x³ + 6x²- 1)

   = (4x³ - 3x³) + (5x² - 6x²) + 3x + 1

   = x³- x² + 3x + 1

oh i hade this i got wrong but the answer is 79

Step-by-step explanation:

Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.

Why it is and what is distance?

To determine the distance Karl traveled by the time he had 200 liters of fuel remaining in his truck, we need to examine the graph provided.

From the graph, we can see that when the fuel remaining in the truck tank is 200 liters, the corresponding distance driven is approximately 420 kilometers.

Therefore, Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.

Distance is the physical length between two points or objects. It is a scalar quantity that measures the amount of space between two locations, without regard to the direction of travel. Distance can be measured in various units such as meters, kilometers, miles, and so on.

In physics, distance is often distinguished from displacement, which is a vector quantity that measures the change in position of an object relative to its starting point.

(A)  I got 10(10)=100 points in remote space.

(B) I also got 10(9)=90 points in remote space

Answer:

a) 100

b) 90

Step-by-step explanation:

For the first question, the first button you press will have 10 possibilities, from 0-9.  For the second button, you will still have 10 possibilities since the same button may be pressed twice. Therefore, you get 10*10=100.

For the second one, the same button may not be pressed twice. For the first button press, you have 10 possibilities, but for the second button, you have 1 less possibility since you aren't allowed to push the button you pressed before. So there will be 9 possibilities. 10*9=90.

Answer:

Read the step-by-step for the entire answer!!!

Step-by-step explanation:

Whenever you have situations like these you have to look at it from the perspective given.

If you are throwing a ball it's going to start at ground 0 where the child is, therefore the height of the child is how high off the ground the ball is at 0 seconds.

If it is thrown, and it is stuck in the tree for a few seconds, then that means on the graph you will see an incline of the graph, and then a stale line for a few seconds as the ball is stuck in the same height for a few seconds.

After the ball falls down, then so will the height of the ball.

t - a function of time, is always on the x-axis because time variables are usually on the x-axis of a graph.

I choose seconds as a measurement of time because in a realistic situation a ball will be in the air for seconds.

h - the height of the ball, will be on the y-axis of the graph because it is a dependent variable (i.e. the height of the ball is dependent on how long the ball is in the air for).      

The image below is the graph.

Answer:

Y = 2x + 4

Step-by-step explanation:

y= mx +b

First, find m (aka the slope)

[tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{1}[/tex] = 2

m = 2

Find b (aka the y-intercept)

The line touches the y-axis at (0,4). Therefore b = 4

Plug m and b into the slope-intercept equation

y = mx +b

y = 2x + 4
