What is equation of the line graphed below. Y= - 5/2 x-2 -this question was accidentally cut out

The y-intercept will be at (0, 22,995) and the x -intercept at (9, 0).

The y-axis is calibrated in dollars and the x-axis in years.

The graph is a straight line which starts  on the positive y axis and ends on the positive x-axis and has a negative slope .

Y - intercept:

The point of intersection is the point on the Y-axis through which the slope of the straight line passes. This is the y-coordinate of the point where the line or curve intersects the y-axis. This is shown when writing the equation for the y = mx + c straight line. where m is the slope and c is the intersection with the y-axis.

X- Intercept:

The x-intercept is the point at which the graph of the equation intersects the x-axis, and the y-value must be 0 for the point to intersect the x-axis. Consequently, the x segment can always be represented as (x, 0). The x value indicates where the graph intersects the x-axis.

According to the question:

When X = 0, y = 22995

And, X = 9  and Y = 0.

So the intercepts are (0,22995) and (9,0) which are shown on the right.

The value of the angle 4 is 96 degrees as shown in the diagram.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things.

From the given diagram, the measure of angle 1 and 3 are equal as well as 2 and 4.

Given the following angles

m<3 = 84 degrees

Since the measure of <3 and <4 lies on the same straight line, hence:

m<3 + m<4 = 180

84 + m<4 = 180

m<4 = 180 - 84

m<4 = 96 degrees

Hence the measure of angle 4 from the figure is 96 degrees

Step-by-step explanation:

the distance from a vertex of the quadrilateral to the touching points on the two sides emanating from the vertex is the same.

and that applies to each of the 4 vertices.

so, AB splits into the distance a (from A to the circle touching point on AB) and b (from the touching point on AB to B).

b = AB - a

in the same way, BC splits into b (B to circle touching point on BC) = AB - a, and c (circle touching point on BC to C).

c = BC - (AB - a) = BC - AB + a

CD splits into c (C to circle touching point on CD) = BC - AB + a, and d (circle touching point on CD to D).

d = CD - (BC - AB + a) = CD - BC + AB - a

DA now splits into d (D to circle touching point on DA) = CD - BC + AB - a, and into ... a (the circle touching point on DA to A).

a = DA - (CD - BC + AB - a) = DA - CD + BC - AB + a

0 = DA - CD + BC - AB

DA = CD - BC + AB = 8 - 5 + 4 = 7

The number of pack Jill needs is 7.

The diagram shows the floor plan of Jill's dining room. Jill is going to cover the floor with wooden floorboards. The floorboards are sold in packs. One pack of floorboards will cover 2.25 m². Therefore, the number of packs Jill needs can be calculated as follows;

Therefore, let's find the area of the floor.

area of the floor  = area of the first rectangle + area of the second rectangle

area of the first rectangle = 3 × 2

area of the first rectangle = 6 m²

area of the second rectangle = 4.5 × 2

area of the second rectangle = 9 m²

area of the floor  = 15 m²

Therefore,

2.25 m² = 1 pack

15 m² = ?

cross multiply

number of pack = 15 / 2.25

number of pack = 6.66666666667

Answer:

Amy is 14 years old and Sam is 10 years old.

Step-by-step explanation:

Let's represent Amy's current age as "A".

Since Sam is four years younger than Amy, his current age can be represented as (A - 4).

Five years ago, Amy's age was A - 5 and Sam's age was (A - 4) - 5 = A - 9.

At that time, Sam was half of Amy's age, so we can write the following equation:

(A - 9) = (A - 5) / 2

Expanding and simplifying the equation, we get:

A - 9 = 2A / 2 - 5 / 2

A - 9 = A - 5 / 2

7 = A / 2

A = 14

So, Amy is 14 years old and Sam is (14 - 4) = 10 years old.

By using the x- and y-intercepts, a graph of the function modeling the total number of tickets sold is shown in the image attached below.

The domain and range of each function is {-∞, ∞}.

The meaning of the x-intercept is that the initial number of student tickets sold is 600 tickets.

The meaning of the y-intercept is that the initial number of adult tickets sold is 300 tickets.

The slope of the function is 0.5 and it represents the number of tickets sold per week.

You can use the graph to determine a combination of ticket sales to meet the goal of $3,000 by adding each ordered pair (s, a) or (x, y) together.

Felina's graph is correct because it has the same x-intercept and y-intercept with the original graph.

In order to write a linear equation to describe this situation, we would a assign variable to the number of student tickets sold and the adult tickets sold respectively, and then translate the word problem into a linear equation as follows:

Since student are paying $5 while adults are paying $10 for a ticket and the athletic association need to raise $3000 by selling tickets, a linear equation that models the situation is given by:

5s + 10a = 3000

When s = 0, the value of a is given by:

5(0) + 10a = 3000

a = 300

When a = 0, the value of s is given by:

5a + 10s = 3000

s = 600

For the total number of tickets, we have this linear equation:

s + a = 450

In conclusion, we would use an online graphing calculator to plot the system of linear equations in order to determine the solution (point of intersection), which is at the ordered pair (300, 150).

Total number of students that like chicken nuggets is 4/7 x G + 40/100 x B.

The percentage of entire student body that like chicken nuggets are (4/7 x G + 40/100 x B) / T x 100.

Given that 4/7 of the girls like chicken nuggets, if there are G girls, then the number of girls who like chicken nuggets is 4/7 x G.

Given that 40% of the boys like chicken nuggets, if there are B boys, then the number of boys who like chicken nuggets is 40/100 x B.

The total number of students who like chicken nuggets is 4/7 x G + 40/100 x B.

A library has 2500 books.40% of the books are fiction, number of not fiction books are 1500.

A percentage is a relative figure that represents one tenth of a quantity. Since one percent (symbolised as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.

Total amount of book in library are 2500 ,

Out of that 40% are fiction so the number of the non fiction books are 60%

so 60% of 2500 will give us the value of non fiction books,

Number of non fiction = 2500 x 60%

A high standard deviation indicates greater variability in the data set. A low standard deviation indicates lower variability in the data set.

A standard deviation is a measure of how spread out the values in a data set are. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. A high standard deviation indicates that the values in the data set are far from the mean and spread out over a large range of values. This suggests that there is a large amount of variation and diversity in the data. On the other hand, a low standard deviation indicates that the values in the data set are close to the mean and spread out over a smaller range of values. This suggests that there is less variability and diversity in the data. A standard deviation of zero indicates that all values in the data set are the same. This suggests that there is no variation or diversity in the data. No one set of data is more accurate than another; accuracy depends on the context and purpose of the data.

You want the surface area of a rectangular prism whose net is shown.

The surface area of the prism is the area of the net. That area is the sum of the areas of the rectangles that make it up. The rectangles come in pairs that have the same area.

Down the middle we have two pairs of rectangles. One pair is 8 cm wide and 3 cm high; the other is 8 cm wide and 5 cm high. Together the area of those four rectangles is ...

  2(8 cm)(3 cm +5 cm) = 2(64 cm²) = 128 cm²

The "wings" of the net are rectangles that are 3 cm by 5 cm, so their total area is ...

  2(3 cm)(5 cm) = 30 cm²

The area of the net is then ...

  surface area = 128 cm² +30 cm²

  surface area = 158 cm²
