Question

Scientists are studying the temperature on a distant planet. Let y represent the temperature (in degrees Celsius). Let x represent the height above the surface (in kilometers). Suppose that x and y are related by the equation 23 - 5x=yNote that a change can be an increase or decrease. For an increase, use a positive number. For a decrease, use a negative number. What is the temperature change for each kilometer we go up from the surface? What is the temperature on the surface of the planet?

Answer 1

Answer:

• For every increase in height, the temperature is -5

• The temperature on the surface is when y = 23

Explanation:

Given the equation:

$23-5x=y$

Where y represent the temperature (in degrees Celsius), and x represent the height above the surface (in kilometers).

For x = 1, we have:

23 - 5(1) = y

y = 23 - 5 = 18

For x = 2, we have:

23 - 5(2) = y

y = 23 - 10 = 13

For x = 3, we have:

23 - 5(3) = y

y = 23 - 15 = 8

For every increase in height, the temperature is -5

The temperature on the surface is when x = 0

23 - 5(0) = y

y = 23
