Some students collected the data below. They will graph the data. What is the y-intercept? Your answer should be an ordered pair ( , )

Answer: 150 percent.

Step-by-step explanation:

The problem asks for the percent increase in the annual student fees from 2000 to 2014.

First, we need to know how to find a percent increase.

The percentage change formula is

(Increase in amount) / (Original amount) * 100

Using this formula, we can solve this problem.

Since the fee in 2000 was $6000 and the fee in 2014 was $15000, we can find the increase in fees.

Increase in fees = 15000-6000 == 9000

Next, let's use the formula to find the answer.

Percentage Increase = (Increase in fees) / (Original amount) * 100

= 9000 / 6000 * 100

= 150

Therefore, the answer is 150 percent.

Beginning at the y-intercept (0,35),Line is solid, slopes down one and over one, and is shaded beneath.

Choose your variables first.

If x is the amount of hours spent mowing lawns,

Let y equal the number of hours worked at the clothes business.

A minimum of $400 must be earned from both employment (400 or more)

15x + 10y ≥ 400

In order to graph y = -15/10x +35, get y.

10 hours minimum every day in the store.

35 hours maximum per week

x + y ≤ 35

To graph y = -x + 35, find y.

Making the graph: 0 to 35 for the x and y axes.

First equation: y = -15/10x + 35 y-intercept = 35 slope: solid line on the y-axis starting at 35, going down 12, over 10 Shade above solid line

Second formula: y 10

At y=10, draw a solid horizontal line; more than should be shaded above the line.

Third formula: y = -x + 35

beginning at the y-intercept (0,35)

Line is solid, slopes down one and over one, and is shaded beneath.

The overlapping region on the graph will appear as a little triangle with its points under the line from the third equation, above the horizontal line, and above the line from the first equation.

The value of the expression P(x) in the function for the weight of a thin water layer between heights x and Δx, P(x)·Δx, is;  P(x) = 47040·x N/m

A function is a rule that defines the relationship between a set of input and outputs variables, such that each input variable is mapped to only one output variable.

The parameters of the right prism are presented as follows;

Height of the isosceles triangular face = 5 meters

Width of the triangle = 4 meters

The length of the right prism = 6 meters

The function for the weight of a thin water layer between height x and height x + Δx = P(x)·Δx

Weight = Density × Volume × Gravity

Volume = Cross sectional area × Height

Cross sectional area = Width × Length = Width × 6

Using similar triangles, we get;

Width, W = (4/5)×x

Therefore; Cross sectional area = (4/5)×x × 6

Weight = Density × Cross sectional area × Gravity × Height

The height of the section = Δx, therefore;

Weight = Density × Cross sectional area × Gravity × Δx = P(x) × Δx

Therefore; Density × Cross sectional area × Gravity = P(x)

P(x) = ρ × (4/5) × x × 6 × g

The density of water, ρ = 1000 kg/m³

g = 9.8 m/s²

P(x) = 1000 kg/m³ × (4/5) × x × 6 m × 9.8 m/s² = 47040·x N/m

To graph the system of equations 3x - 2y = 4 and 3x + 2y = 8, we first need to solve for the value of x and y.

To solve for x and y, we can use the first equation 3x - 2y = 4,

3x - 2y = 4

y = (3x/2) - 2

we can substitute this value of y into the second equation 3x + 2y = 8

3x + 2(3x/2 - 2) = 8

3x + 3x - 4 = 8

6x = 12

x = 2

Now we can substitute the value of x into the first equation to find the value of y

3(2) - 2y = 4

6 - 2y = 4

-2y = -2

y = 1

so the point of intersection is (2,1)

In order to graph the system of equations, we can plot the point of intersection (2,1) and then use the slope-intercept form of the equations to graph the lines.

The slope-intercept form of the first equation is y = (3/2)x - 2

The slope-intercept form of the second equation is y = (1/2)x + 4

So, the lines have a slope of 3/2 and 1/2 respectively.

We can now plot these lines on the coordinate plane, with the point of intersection (2,1) being the point where the lines cross.

The graph of the system of equations is the two lines crossing at the point (2,1)

The unknown angle in the intersecting secant is as follows:

m∠GPE = 27 degrees

Secant is a line that intersects a curve at a minimum of two distinct points.

Using angle of intersecting secant theorem, the angle made by two secants (a line that cuts a circle at two points) that intersect outside the circle is half of the furthest arc minus the nearest arc.

Therefore, m∠GPE can be found as follows;

Hence,

m∠GPE = 1 / 2 (mGE - mHF)

mGE = 97 degrees

mHF = 43 degrees

Therefore,

m∠GPE = 1 / 2 (97 - 43)

m∠GPE = 1 / 2 (54)

m∠GPE =54 / 2

When the number of blue frogs increased by 60% and the number of green frogs decreased by 60%, the percentage of the overall increase is solved to be 60%

Assuming the number of blue frogs and the number of green frogs are equal and = y

Then the total number of frogs = y + y = 2y

Increasing the percentage of each by 60%, the factor for percentage increase by 60% is 1.6

hence 1.6y + 1.6y = 3.2y

percentage change

= change in price / original price * 100

Using substitution method, the values of a and b in the system of linear equations are 6.3 and 3.65

A system of linear equations is a set of two or more linear equations that contain two or more variables. The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system simultaneously. Linear equations are equations that can be written in the form of ax + b = y, where a, b, and x are constants and x is the variable.

To solve this problem, we have to solve the equations simultaneously using either substitution or elimination method.

0.95a + 1.1b = 10 ...eq(i)

a + b = 9.95 ...eq(ii)

From equation (ii)

a + b = 9.95

The shape of the ABCD is a rhombus. The diagonals are not equal to each other.

What is the 2-dimensional shape?

A two-dimensional shape with horizontal and vertical axes is known as a 2d shape (x-axis and y-axis). Two-dimensional shapes have only length and width. There is no thickness or height to these shapes.

Given the vertices of ABCD are  A(-3,0), B (1,5), C(-3,10) and D(-7,5).

The formula distance between points (x₁, y₁) and (x₂, y₂) is √[(x₂ - x₁)² + (y₂ - y₁)²].

The distance between A and B is √[(1 - (-3))²+(5 - 0)²] = √(4²+5²) = 6.4

The distance between B and C is √[(-3 - 1)²+(10 - 5)²] = √(4²+5²) = 6.4

The distance between C and D is √[(-7 - (-3))²+(5 - 10)²] = √(4²+5²) = 6.4

The distance between A and D is √[(-7 - (-3))²+(5 - 0)²] = √(4²+5²) = 6.4

The distance between A and C is √[(-3 - (-3))²+(10 - 0)²] = √(10²) = 10

The distance between B and D is √[(-7 - 1)²+(5 - 5)²] = √(8²) = 8

The slope of a line passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).

The slope of AB is (5-0)/(1-(-3))=5/4

The slope of BC is (10-5)/(-3-1)=-5/4

The slope of CD is (5-10)/(-7-(-3))=5/4

The slope of AD is (5-0)/(-7-(-3))=-5/4

The number of vertices of the quadrilateral is 4.

Thus it is either a square or rectangle or rhombus or parallelogram.

Since the length of all sides is equal thus it is either a square or rhombus.

Since the diagonals are not equal it is a rhombus.

A cyclic quadrilateral is a four-sided shape whose vertices all lie on the same circle. This means that all four angles of the quadrilateral are equal to one another.

This is further explained by circle theorem which is a branch of mathematics that deals with the properties of circles and their relationships with other shapes. It is based on the fact that all points on a circle are equidistant from the center of the circle. Circle theorem has many applications, such as finding the area of a circle, calculating the circumference of a circle, and even determining the angles of a triangle formed by three points on a circle.
