The segment goes from point (-1, 3) to (1,-1)
Slope = rise / run = (-3 - 1) / (1 - (-1)) = -4 / 2 = -2
Slope = -2
The question is incomplete. Here is the complete question:
During ski season,the owner of ski shop has determined that the number of customers in a day is greater than or equal to 50 more then the temperature(Fahrenheit)
. Write an inequality for the problem and determine the constraints on the variables.
Answer:

Step-by-step explanation:
Let the number of customers be 'N' and the temperature in Fahrenheit be 'T'.
Given:
Number of customers is related to temperature in Fahrenheit as:
Number of customers is greater than or equal to 50 more than the temperature in Fahrenheit. This means,

Now, since 'N' represents number of customers and number can never be a negative quantity. So, the only constraint for this inequality is that the number of customers must be greater than or equal to 0.
So, 
Answer:
The probability of the heads up on the first three flips and not on the last two flips will be 1/32.
Step-by-step explanation:
As, the probability of head up when one time coin is flipped is 1/2. And it is said in the question that you must get heads in the first three flips.
So, for the first three flips the probability is = (1/2)^3 = 1/8
And for the last two flips you want to get not heads up.
Then, the probability is = (1/2)^2 = 1/4
Hence, your overall probability will be = 1/8 × 1/4 = 1/32 .
Answer:
Prism A:

Prism B:

Step-by-step explanation:
Given
See attachment for prisms

Required
Determine the surface area of both prisms
Prism A is triangular and as such, the surface area is:

Where

and

Such that a, b and c are the lengths of the triangular sides of the prism.
From the attachment;

So, we have:




Also:




So:



Prism B is a rectangular prism. So, the area is calculated as:

From the attachment


So:
