Mathematics

Alchen [17]3 years ago

Answer: Hello mate!

The partition of a set is defined as a partition of the set into a nonempty subset, where the set itself is a subset of himself, then the set is a partition of himself.

a) in this we have a set of two objects; A = (1,2) the partitions of this set are: (∅), (1), (2) and (1,2). Where (∅) is the null set.

b) Now we have a set of three objects; B = (a,b,c) the partitions of this set are: (∅), (a), (b), (c), (a,b), (a,c), (b,c), (a,b,c)

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2),
astraxan [27]

Answer:

k = 1

Step-by-step explanation:

Given

3y = 5x + k

Opposite points: (1,-2) and (-2,1)

Required

Find k

First, calculate the midpoint of the opposite points.

(x,y) = 0.5(x_1 + x_2,y_1 + y_2)

This gives:

(x,y) = 0.5(1 -2,-2 + 1)

(x,y) = 0.5(-1,-1)

Open bracket

(x,y) = (-0.5,-0.5)

The equation 3y = 5x + k becomes:

3 * -0.5 = 5 * -0.5 + k

-1.5 = -2.5 + k

Solve for k

k = 2.5-1.5

k = 1

Combine the like terms to create an equivalent expression 5n-2n
inysia [295]

Answer:

The answer is 3n

Step-by-step explanation:

Since the expression has two numbers with the same variable, they are able to be combined.

We will subtract 2n from 5n, so 5n - 2n.

This results us with <u>3n</u>, since 5 - 2 equals 3.
