40 x 0.08875 = 3.55
40 + 3.55 = 43.55
the sum is $43.55
Answer:
Slope = -3
y-intercept = (0,-4)
Equation: y = -3x-4
Step-by-step explanation:
We can take any two input-output pairs from the table to find the equation of given function.
Linear function is given by:

Here m is the gradient of the functions which is defined as:

The input-output pairs are:
(x1,y1) = (-1,-1)
(x2,y2) = (0,-4)
First of all,

Putting the value of slope in the equation

Putting (-1,-1) in the equation

The equation will be:

Hence,
Slope = -3
y-intercept = (0,-4)
Equation: y = -3x-4
100 meters is -1°C
1,000 meters is -10°C
10,000 meters is -100°C
And 2,000 meters is -20°C
12Km is 12,000 meters
12,000 meters is -120°C
Your answer is -120°C
