Mathematics
1 answer:
WITCHER [35]3 years ago
3 0

Answer:

c.) x = 3

Step-by-step explanation:

2x - 3y = 9

x = 4 + y

Substitute the second equation into the first equation

2(4+y) - 3y = 9

Distribute

8+2y -3y =9

8-y = 9

Subtract 8 from each side

8-y-8 =9-8

-y = 1

Multiply by -1

y =-1

Now solve for x

x = 4-1

x =3

Let S be the universal set, where:
kolezko [41]

A' = {7,8,10}

B' = {1,3,59}

Given,

Let S be the universal set, where:

S = {1,2,3,4,5,6,7,8,9,10}

Let sets A and B be subsets of S, where:

Set A = {1,2,3,4,5,6,9}

Set B = {2,4,6,7,8,10}

We need to find the elements in the set (A') and (B)'

<h3>What is a complement of a set?</h3>

A compliment of a set D is denoted by D' or D bar.

It means the set contains all elements in the universal set U other than the elements in set D.

Example:

U = {1,2,3,4,5,6,7,8,9}

D = {1,2,3,4,5}

D' = {6,7,8,9}

Find A' and B'

S = {1,2,3,4,5,6,7,8,9,10}

A =  {1,2,3,4,5,6,9}

B = {2,4,6,7,8,10}

A' = {7,8,10}

B' = {1,3,59}

Thus,

A' = {7,8,10}

B' = {1,3,59}
