Answer:
Invalid in tha way from a and b we can conclude c.
In the other way, from a and c we can NOT conclude b.
Step-by-step explanation:
We have 3 sets: 1.people who can tell a valid argument from an invalid one
2.thoughtful people and 3.discrete mathematics.
From a. we concluded that 2. set is subset of 1. set.
From b. we concluded that set 3. is subset of set 2.
Now we know that set 3. must be subset of the set 1. That implicate that c is valid. (diagram 1)
If we want to conclude from a and c the b, it is not possible, because we dont have all informations.
From a. we know thah set 2. is subset od set 1.
From c. we know that set 3. is also subset of set 1.
But it does not follow that 3. is subset of set 2. (diagram 2)
Answer:
The Slope of both the lines is the same.
Step-by-step explanation:
Given two co-ordinates (x1, y1) and (x2, y2), the slope of a line can be found using the formula:
For the diagonal line of the first triangle, the coordinates are (0, 0) and (2, 1)
For the diagonal line of the large triangle, the coordinates are (2, 1) and (6, 3)
