Solve -2=4r+s solve for s please.

Answers

Answer 1

Answer: -2=4r+s
-2-4r=s
s=-4r-2
To solve for "s", you'd need a value for the "r" variable. This is the simplified version of an equation.

Answer 2

Answer: S = -2-4r. You can't simplify the expression past that.

B. The mean is decreased by about 0.7 and the median is decreased by 3. C. The mean is decreased by about 1.2 and the median is decreased by 2. D. The mean is decreased by about 1.2 and the median is decreased by 3.

Answers

The correct answer for the question that is being presented above is this one: " C. The mean is decreased by about 1.2 and the median is decreased by 2." For the data shown in the stem-and-leaf plot, the effect on the mean and median of adding the value 10 to the data set is that the mean is decreased by about 1.2 and the median is decreased by 2.

Adam builds model rockets. Where he lives , his backyard is 12 feet below sea level. When he ignites his rocket, it flies a maximum of 350 feet straight up into the air before releasing its parachute. What is the altitude of adams rocket at its highest point, as measured from sea level?

Answers

Answer:

The answer is 338 feet.

Step-by-step explanation:

Adam builds model rockets. Where he lives , his backyard is 12 feet below sea level.

The rocket flies a maximum of 350 feet straight up into the air before releasing its parachute.

So, the altitude of Adams rocket at its highest point, as measured from sea level = $350-12=338$ feet

350 _ 12= 338 ft above sea level.

Julian and stacey needed 10 liters of water to fill a tank. Stacey filled the tank with 3 11/12 liters of water. Julian poured 1 2/5 liters less than Stacey into the tank. How much more water is still needed to fill the tank?

Answers

The amount of water Julian and Stacey needed to fill the tank = 10 liters
Amount of water filled by Stacey individually = 3 11/12 liters
   = 47/12 liters
It is given in the question that Julian poured 12/5 liters less than Stacey.
Then Amount of water filled by Julian = (47/12) - (12/5) liters
      = (235 - 144)/60
   = 91/60
So Julian filled 91/60 liters of water in the tank.
Amount of water still needed to fill the tank = 10 - [(47/12) - (91/60)]
   = 10 - [(235 - 91)/60]
   = 10 - (144/60)
   = 10 - 12/5
   = (50 - 12)/5
   = 38/5
   = 7 3/5
so 7 3/5 liters of water is still required to fill the tank.

Provide an Example of how to draw transformed figures that are translated, reflected, and rotated.

Answers

Step-by-step explanation:

Translations: When a figure is slid to another place on the coordinate grid (for example if i asked you to move the figure 2 units down and 4 units to the left)

Reflected: When a figure is reflected across the y-axis or the x-axis and both figures are congruent to each other.

Rotated: When a figure is rotated (for example if i asked you to rotate the figure 90 degrees)
