n T = 456 − 3 The equation above is used to model the relationship between the number of cups, n, of hot chocolate sold per day
1 answer:
Answer:
3 represents: For every decrease of 1°F, three more cups of hot chocolate will be sold.
Step-by-step explanation:
Consider the provided equation.
The relationship between the number of cups, n, of hot chocolate sold per day in a coffee shop and the average daily temperature, T, in degrees Fahrenheit.
The provided equation can be written as:
If we observe we can find that the above model is same as the slope intercept form . Where m is the slope.
Therefore, -3 represents the slope of the function.
The "minus" sign represents the slope of line is downward.
If we Substitute T=0 in provided equation we get N=456
That means when temperature is 0 degrees Fahrenheit the number of cups (N), of hot chocolate sold per day in a coffee shop is 456.
If we Substitute T=1 in provided equation we get N=453
If we Substitute T=-1 in provided equation we get N=459
Therefore, If we increase temperature the number of cups decreases.
Hence, the meaning of 3 in equation is: For every decrease of 1°F, three more cups of hot chocolate will be sold.

Taking commen 2 in RHS
p = 2 (L+W )
Divide by 2 on both sides.
p/2 = L+W
Subtract W on both sides.
p/2 - W = L
or L = p/2- W
