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
Svetradugi [14.3K]

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.

N= 456-3 T

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:

N= -3T+456

If we observe we can find that the above model is same as the slope intercept form y=mx+c. 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.

An ice skating show earned 15,385 in one night. Tickets for the show cost $25 for adults and $15 for children. The number of adu
Degger [83]

Answer:

Number of adults that attended the show = 400

Number of children that attended the show = 359

Total people who attended the show = 759

Step-by-step explanation:

Total earned = 15,385

Adults = $25

Children = $15

Let

Adults = A

Children = C

The number of adults who attendee the show was 41 more than the number of children who attended the show

A = C + 41

25A + 15C = 15,385

Substitute

A = C + 41

25(C+41) + 15C = 15,385

25C + 1,025 + 15C = 15,385

40C + 1,025 = 15,385

40C = 15,385 - 1,025

40C = 14,360

Divide both sides by 40

C = 14,360 / 40

= 359

C = 359

Substitute C = 359 into

A = C + 41

A = 359 + 41

= 400

A = 400

Number of adults that attended the show = 400

Number of children that attended the show = 359

Total people who attended the show = 759

Eliminate the parameter
Pani-rosa [81]

Option 1. y = 3x^{2} +7 is obtained by eliminating the parameter.

Step-by-step explanation:

Step 1:

We have that x = \sqrt{t} and y = 3t+7.

Take x = \sqrt{t} as equation 1.

Assume y = 3t+7 is equation 2.

We need to determine a value that is equivalent to t so it can be substituted in equation 2.

Step 2:

If we square equation 1, we get

x^{2}  = (\sqrt{t})^{2} , x^{2}  =t .

So we have a value that can replace t, so we substitute this is equation 2.

y = 3t+7, x^{2}  =t, so

y = 3x^{2} +t which is the first option.
