Answer:
m = 1/6
Step-by-step explanation:
use the slope formula
I believe the answer 12p^2
It said here the temperature drops 6.5°C when an altitude increases 1 kilometer and the bottom of the troposphere is about 15°C
Take the second equation and solve for y.
y - 3 = x
y = x + 3
Substitute this back into the first equation and solve for x.
x + 3 = x^2 + 3.
x = 0.
Plug this into either equation to get y.
This will be give a solution of...
x=0, y=3
