-20 because after the the thermometer hits zero the more negative the temperature gets the colder it is
I believe that the answer is c but if you wanted to make sure you could figure out the correlation on a graphing calculator.
Answer: The fraction would be 0.53.
Step-by-step explanation:
Since we have given that

where, A is the constant initial production rate
t is the time.
For 98 years, the production rate in motorcycles per year would be

For 13 years, the production rate in motorcycles per year would be

So, the fraction of their total production was built during the last 13 years would be

Hence, the fraction would be 0.53.
Perpendicular lines have negative reciprocals. This means that if you multiply the slopes of both lines, the product will be a -1.
In your given point-slope equation, the slope is 1/3. Therefore, the negative reciprocal of 1/3 must be -3.
Out of the given options:
y + 2 = -3(x — 4)
y = -3x - 5
are the linear equations that are perpendicular to y — 1 = 1/3(x + 2).
Therefore, the correct answers are Options 1 and 3.
