Answer:
D.f=288.68
Step-by-step explanation:
f+ 523.89 = 812.57
subtract 523.89 from both sides
f+ 523.89-523.89 = 812.57-523.89
f = 288.68
Answer:

Find the value of b
using the formula for the equation of a line.
b
=
11
Now that the values of
m (slope) and b
(y-intercept) are known, substitute them into
y
=
m

b to find the equation of the line. y

slope = (y2-y1)/(x2-x1)
= (70-52)/(8-1)
= 18/7
=2.6
point slope form
y-y1 = m(x-x1)
y-52 = 2.6(x-1)
distribute
y-52 = 2.6x-2.6
add 52 to each side
y = 2.6x+49.4
y = 2.6x +49
the initial temperature is 49.4 or about 49
and it increases about 2.6 degrees each week
