Answer with Step-by-step explanation:

We are given that two sets  A and B

A\subset B

We have to prove show that A\cap B=A\cup B

Suppose , x belongs to [tex}A\cap B[/tex]

Then , x\in A,x\in B

Then, x\in (A\cup B)

If, x\in (A\cup B)

Then, x\in A or x\in B

If x\in B Then, it is not necessary that x belongs to  A .

If x belongs to A then

A\cap B=(A\cup B)

If x does not belongs to A then

A\cap B \neq(A\cup B)

But, if x belongs to A then x is also belongs to B because  A is a subset  of B.

Then, A\cap B=(A\cup B)

Alyssa, Bart and Meghan are
adoni [48]

Hi,

Essentially, we are saying that Alyssa gets 5 parts of the whole thing (140,000), Bart gets 3 parts of the whole and Meghan gets 2 parts of the whole. The sum total of their parts = the whole. So now we need to find out how much one part is. Thus,"one part" should be the variable. Substitute p for "one part", so Alyssa gets 5p, Bart gets 3p, and Meghan gets 2p. Since the sum of the parts = the whole, your problem sets up as:  5p + 3p + 2p = 140,000  -->  10p = 140,000 --> 10p/10 = 140,000/10  -->  x = 14,000.

Alyssa gets 5p or (5 x 14,000)

Bart gets 3p or (3 x 14,000)

Meghan gets 2p or (2 x 14,000)

If the whole was a loss, it would be a negative, and instead of getting money, they would lose money.

Can someone please help me with this? I’m really confused on it.

For this problem you need to put the x values in for x in the equation. For example, put -10 in for x and calculate y, which is g(x)

A company makes a profit of $7 per software program and $8 per video game. The company can produce at most 90 software programs
g100num [7]

Answer:

930 dollars

Step-by-step explanation:

Let software programs = S

Video game = V

Given that a company makes a profit of $7 per software program that is, 7S and $8 per video game that is, 8V. The company can produce at most 90 software programs and at most 80 video games per week. Since the Total production cannot exceed 120 items per week.

How many items of each kind should be produced per week in order to maximize the profit?

The to get profit P

P = 7S + 8V

Since the profit on video game is higher, we will give maximum production to video game. Therefore,

P = (30 × 7) + ( 8 × 90)

P = 210 + 720

P = 930 dollars
