Answer:

The domain of R is {-3,-2,1,-3,0}

The range of R is: {2,1,3}

The relation R is not a function

Step-by-step explanation:

Relations and Functions

We are given the ordered pairs of a relation, let's call it R:

R={(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}

The domain of R is the set of values that relate to 1 or more elements from the range.

The domain of R is {-3,-2,1,-3,0}

The range of R is: {2,1,3}

Note the value 2 is repeated in the second set, but it's reported only once as part of the Range.

A relation is a function if each element of the domain appears in only one ordered pair, or relates to a single element in the Range.

The relation R is not a function, because the ordered pairs (-3, 2) and (-3, 1)

map the element -3 twice.

Answers

m = (y2-y1)/(x2-x1)

m = (9-5)/(3-2)

m = 4

Substitute the values in y= mx + c,

5 = (4)(2) + c

5 = 8 + c

c = -3

Thus, the equation is y= 4x -3

The y intercept is -3 and the slope of line is 4 .

Then the equation of line will be : y= 4x -3

Given,

Points on x and y axis .

Standard equation of line :

y = mx + c

m = slope of line

c = y intercept

Now

Firstly find out the slope of line ,

m = (y2-y1)/(x2-x1)\

m = (9-5)/(3-2)

m = 4

Now to calculate the value of y intercept

Substitute the values in y= mx + c,

5 = (4)(2) + c

5 = 8 + c

c = -3

Thus, the equation is m = (y2-y1)/(x2-x1)

Lin-Manuel runs a rare book store. Last year, he earned $35,000 in revenue and had explicit costs of $8,000. Lin-Manuel could have made $29,750 testing information security equipment and received an additional $10,000 if he had used the company's inputs in a different way. Calculate Lin-Manuel's economic profit.

Answers

Answer: Economic loss of $12,750

Step-by-step explanation:

Economic profit is calculated by deducting both the implicit and the explicit costs from income.

Explicit cost are the costs of running the business whilst implicit costs are the gains that could have been earned if other alternatives had been embarked on.

Economic profit (loss);

= 35,000 - 8,000 - 29,750 - 10,000

= (12,750)

Given that 2x + 1 =5, what is the value of (x+3)^3

Answers

Answer: 125

Step-by-step explanation:

First, solve for x in the first equation.

1) Subtract 1 from both sides.

2x = 4

2) Divide by 2 on both sides.

x = 2

Next, substitute the value of x into the second expression.

(2 + 3)^3

= 5^3

= 125

Answer:

The value of (x + 3)³ is 125.

Step-by-step explanation:

First, we have to find the value of x.

To do so, start with the first equation, 2x + 1 = 5.

We can easily solve this equation to find the value of x.

First, start by subtracting 1 from each side.

This leaves us with 2x = 4.

Next, divide by two on each side.

This will leave us with the answer x = 2.

Now we know the value of x = 2.

All that's left to do is substitute the value of x, 2, for x.

First, start with the second equation (x + 3)³.

We know that x is equal to 2, so we can enter 2 for x.

We then have the equation (2 + 3)³.

Next, solve.

Add the 2 and the 3 together.

Now, the equation is 5³.

5³ is equal to 5 · 5 · 5

5 · 5 · 5 = 125

To sum up,

We found out that x = 2

Using 2 for x, we found out that (x + 3)³ is equal to 125.

The parallelogram pictured below has a perimeter of 129. Find the value of y.

Answers

Answer:

y = 2½ = 2.5

Step-by-step explanation:

From the question given above, the following data were obtained:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

The perimeter of a parallelogram can be obtained by using the following formula:

Perimeter = 2(a + b)

Thus, with the above formula, we can obtain the value of y as shown below:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

Perimeter = 2(a + b)

Perimeter = 2a + 2b

129 = 2(10y – 9) + 2(17y + 6)

Clear bracket

129 = 20y – 18 + 34y + 12

Collect like terms

129 + 18 – 12 = 20y + 34y

135 = 54y

Divide both side by the coefficient of y i.e 54

y = 135/54

y = 2½ = 2.5

Thus, the value of y is 2½ or 2.5
