Answer:
Step-by-step explanation:
y = 9 - X   is a linear function; x is to the first power.
y = x2 + 1   does NOT represent a linear function; it's a quadratic function.
o             
y=x² + 5    does NOT represent a linear function; it's a quadratic function.
D)
y = [xl - 9  does NOT represent a linear function; it's an absolute value function.  This function has two halves, each of which is a linear function.
But the best answer here is that y = 9 - X   is a linear function; x is to the first power.

Answer:
I gotcha.
Step-by-step explanation:
Condensation - water which collects as droplets on a cold surface when humid air is in contact with it.
Pressure - continuous physical force exerted on or against an object by something in contact with it.
Temperature - the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
Thermal energy - (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
