Answer:
Step-by-step explanation:
The temperature at a given altitude is
y = 36 - 3x
The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.
y = 36 - 3*0
y = 36
So at the surface of the planet is 36 degrees C.
======================
Effectively it is the slope of the equation which is - 3
So ever km going up will mean a loss of 3 degrees. I think they want you to write -3
Required area of shaded portion
= Area of square ABCD - 4 × area of one quadrant

Answer:
508.68
*sorry if this is late
Step-by-step explanation:
Divide 36 by 2 to get radius
Multiply 18 by itself to get 324
Multiply 324 by 3.14 to get the area of a circle
Divide it by 2 to get the area of the semi circle
Step-by-step explanation:
everything can be found in the picture
Answer:
B. The system of equations has no solution.
Step-by-step explanation:
Parallel lines never touch, in order for a system of equation to have a solution the two equations have to intersect, because parallel lines never intersect the system of equations that Presley graphed would have no solution
