The system of inequalities is x + y ≤ 300, 11x + 15y ≥ 3630, x ≥ 0 and y ≥ 0 while the three points are (70, 200), (150, 140) and (140, 150)

From the question, we have the following parameters that can be used to determine system of inequalities

Represent the adult with y and the students with x

So, we have the following representations

x + y ≤ 300 ---- the ticket holders cannot exceed the capacity

11x + 15y ≥ 3630 --- the total sales cannot be less than $3630

x ≥ 0 -- the number of students cannot be negative

y ≥ 0 -- the number of students cannot be negative

Write out the inequalities

x + y ≤ 300

11x + 15y ≥ 3630

x ≥ 0

y ≥ 0

Next, we represent the inequalities on a graph

See attachment for the graph of the inequalities

To get the combination, we make use of the coordinate points that are in the shaded region of the graph

Using the above as a guide, we have

The length of the diagonal of the napkin is 11 inches.

Here, we are given that a square napkin has a side of length 8 inches.

All the sides of a square are equal and the measure of angle formed by any two adjacent sides is also equal and 90°.

Thus, by using Pythagoras theorem, we can form the following equation-

[tex]side^{2} + side^{2} = diagonal^{2}[/tex]

Let the diagonal of the square be d. Then, we have-

[tex]8^{2} +8^{2} =d^{2}[/tex]

64 + 64 = [tex]d^{2}[/tex]

128 = [tex]d^{2}[/tex]

[tex]d^{2}[/tex] = 128

d = [tex]\sqrt{128}[/tex]

d = [tex]8\sqrt{2}[/tex]

the value of [tex]\sqrt{2}[/tex] is approximately 1.41. Thus,

d = 8 × 1.41

= 11.28

Thus, the length of the diagonal of the napkin to the nearest inch comes out to be 11.

f(10) is a multiple of 12 because f(x) has a linear factor of x+2 and x+2 = 12, when x = 10

f(10) multiple of 12 is given as:

The first-degree equations that make up a polynomial's linear factors serve as the foundation stone for higher-order and more complicated polynomials. The formula for a linear factor is ax + b, and it cannot be factored further. When paired with other linear factors, each linear factor represents a separate line, resulting in several sorts of functions with progressively more intricate graphical representations.

f(10) = (10+2)(100+20+2)

= (12)(122)

= 1220+244

= 1464

Bar chart

For 20 charterers

Answer:

$7,000

Explanation:

To find the simple interest on any principal, we use the formula:

From the given question:

• Principal = $50,000

• Rate= 7%

• Time = 2 years

Therefore:

The simple interest is $7,000.

Part a: The relationship between x and y can be represented as y = 6.36 + 1.93x

Part b: The relationship between x and y is proportional

Part c: The value of the card in 2007 will be $25.66

Worth of the card in 1997 = $6.36

Increase in value each year = $1.93

Let x be the number of years the player has been in retirement and y be the value of the cards in dollars

Formulating the equations we get the following:

Value of the card = Worth of the card in 1997 + Increase in value each year*Number of years the player has been in retirement

Part a:

y = 6.36 + 1.93x

Part b:

The relationship between x and y is proportional as the increase in the value each year leads to an increase in the worth of the card

Part c:

Value of the card in 2007:

The number of years the player has been retired will be 10 years in this case

Formulating the equation we get the following:

y = 6.36 + 1.93(10)

= 25.66

So, the value will be $25.66

The gross monthly income range to be for you to be able to rent this apartment is $1671 - $2340.

Let the monthly income be x.

Therefore, 25% of x = 585

0.25x = 585

Divide

x = 585/0.25

x = $2340

The maximum income is $2340.

The minimum income will be:

35% of x = 585

0.35x = 585

Divide.

x = 585 / 0.35

x = $1671

In this case, the minimum value is $1671 and the maximum value is $2340. This illustrates the concept for finding the range.

Answer:   12 feet

This is because [tex]12^2 = 12*12 = 144[/tex]

Squaring a number means you multiply it with itself.

The square root goes in reverse to have [tex]\sqrt{144} = 12[/tex]

Answer:

Each side is 12 ft long.

Step-by-step explanation:

So, you have a square, which means all of the sides are going to be the same length. So, you need something times itself that equals 144. Or, you need the square root of 144 (Because when something is squared, it is multiplied by itself). And the square root of 144 is 12.

Using proportions, the inequality that could be used to determine if a model's height is within the designer's preferred height range is of:

67 inches ≤ Height ≤ 73 inches.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division, from the unit rates in the context of the problem.

One example of application of proportions is for conversion of units, as there are rates for each unit.

In the context of this problem, the rate used is:

1 feet = 12 inches.

Hence the measure of 5'10" = 5 feet and 10 inches is given by:

5 x 12 + 10 = 60 + 10 = 70 inches.

The heights that are within 3 inches of 70 inches are given by:

Hence the inequality that models the situation is:

The equation of the line which passes through point (-5,20), with a slope of -3 is y = -3x + 5.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point ( -5,20 )

First, we find the y-intercept 'b', by plug the slope m ( -3 ) and point  ( -5,20 ) into the equation of line formula and solving for b.

y = mx + b

20 = (-3)(-5) + b

20 = 15 + b

b = 20 - 15

b = 5

Now that both the slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.

y = (-3)x + 5

y = -3x + 5

Therefore, the linear equation of the line is y = -3x + 5.

Answer:

Step-by-step explanation:

$220=$10x+$50

x= hours

subtract $50 from both sides making sure to cancel the right side

$220-$50=$10x

$170=$10x

Divide both sides by $10 to leaving x by itself on the right side

$170/$10=x

17hrs=x

The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Cost of new pair of shoes = $220

In order to earn money for this, Keandre babysits his neighbor for $10 an hour.

And, He also has saved up his monthly allowance which totals $50.

Now,

Let number of minimum hours = x hour

So, We can formulate;

⇒ $10x + $50 = $220

Solve for x as;

⇒ $10x + $50 = $220

Subtract 50 both side, we get;

⇒ $10x + $50 - $50 = $220 - $50

⇒ $10x = $170

Divide by 10 both side, we get;

⇒x = 17

Thus, The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.

To solve the question, we will follow the steps below:

To find f(f(x)), we will simply replace x by x² - 1 in the function x² - 1

That is:

f((fx)) = (x²-1)² - 1

Then we open the parenthesis

f(f(x)) = (x² - 1)(x² -1) - 1

=x²(x²-1)-1(x²-1) - 1

= x⁴ - x² - x² + 1 - 1

= x⁴ - 2x²
