Question

Beneath earths surface, the temperature increases 10 degrees Celsius every kilometer. Suppose That the surface temperature is 22 degrees Celsius, and the temperature at the bottom of a coal mine is 45 degrees celcius. Which equation could be used to find the depth
d. of the coal mine?
a. 10d+22=45
b. 45d-10=22
c. d=22+10
d. 22=10d+45

Answer 1

A

y=mx+b
y=end temperature
10=m(rate)
b=22 the start point/y intercept
d=depth
45=10d+22
rewrite as 10d+22=45
