Find the difference quotient of f

Answer:

Step-by-step explanation:

Given system:

Solve by substitution:

We got correct equation without variables.

It means the equation is correct for any value of variables, the lines are same and overlap.

So there are infinitely many solutions.

Answer:

x = -3

y = 7

Step-by-step explanation:

4y + 2 = 30

x - 4y = -31

Simplify the first equation by subtracting 2 from both sides:

4y = 28

Divide both sides by 4

y=7

Plug 7 in for y to solve for x:

x - 4(7) = -31

x - 28 = -31

Add 28 to both sides

x=-3

(x,y)=(-3,7)

Given:

[tex]X = {0,1,2,3,4} \\ Y = {2,4,6,8,10,12} \\ Z = {3,6,9,12,15}[/tex]

So,

[tex]X∪Y = (0,1,2,3,4) \: ∪ \: (2,4,6,8,10,12) \\ = > (0,1,2,3,4,6,8,10,12)[/tex]

[tex]X∩Z = (0,1,2,3,4) \: ∩ \: (3,6,9,12,15) \\ = > (3)[/tex]

[tex](X∪Y)∩Z = (0,1,2,3,4,6,8,10,13) ∩ (3,6,9,12,15) \\ = > (3,6)[/tex]

Using the generic set operations, we will see that:

For two given sets A and B, we define:

A ∪ B as the union of the two sets, this is the set that contains all the elements from both A and B.

A ∩ B is the intersection of A and B, this set contains only the common elements of A and B.

Now we want to complete the given table:

1) X U Y is the union of sets X and Y (we do not repeat elements) so this is equal to:

{0, 1, 2, 3, 4, 6, 8, 10, 12}

2) X ∩ Z is the intersection of X and Z, the only common element between these sets is 3, then:

X ∩ Z = {3}

3) (X U Y)∩ Z

Is the set of the common elements between:

X U Y = {0, 1, 2, 3, 4, 6, 8, 10, 12}

Z = {3, 6, 9, 12, 15}

The common ones are:

3, 6, and 12, then we have:

(X U Y)∩ Z = {3, 6, 12}

The new value would be the starting value x 1 + interest rate:

New value = starting value x 1.06

The new value is 530:

530 = starting value x 1.06

Find the starting value by dividing the new value by 1.06:

start value = 530/1.06

Start value = 500

Answer: $500.
explain reasoning: because the bond is only one year old you would multiply the value of the bond by the interest rate and add the interest amount to the bond to get $530.

The amount of stickers bought in the sticker exchange is an illustration of factors

There were 47 people in the sticker exchange

The number of stickers is given as:

Stickers = 141

Next, we list the factors of 141 in pairs

(x,y) = (1,141), (3,47), (47,3) and (141,1)

Each person bought more than 1 sticker.

So, we have:

(x,y) = (3,47) and (47,3)

Hence, we can conclude that there were 47 people in the sticker exchange

Answer:

Rate of change per year = $5300

Step-by-step explanation:

Step 1: Substitute the variable P for the invested amount

    1. A(t) = 5000(1.06)t

    2. A(t) = (5300)t

Step 2: Substitute the variable t for the first 15 years

    1. A(15) = (5300)(15)

    2. A(15) = 79,500

Step 3: Substitute the variable t for the 20 years

    1. A(20) = (5300)(20)

    2. A(20) = 106,000

Step 4: Find your two ordered pairs and relation

    First ordered pair: (15, 79,500)

    Second ordered pair: (20, 106,000)

    Relation: {(15, 79,500), (20, 106,000)}

Step 5: Find the slope or rate of change between 15 and 20 years

    Let (y₁, x₁) = (15, 79,500)

    Let (y₂, x₂) = (20, 106,000)

    1. Use the slope expression: y₂ - y₁/x₂ - x₁

    2. Substitute the correct values into the expression:

         106,000 - 79,500/20 - 15

    3. Simplify: 26500/5 = 5300

    4. Hence, the rate of change in dollars per year is $5300
