Which graph represents the function y = 2x - 4?

Answer:

2,000

4,000

7,000

put points on (2, 2,000) - (4, 4,000) - and (7, 7,000)

Step-by-step explanation:

The system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

As we know, if the two linear equations have the same coefficient of x and y they are dependent or if the graph of two linear equations is the same then the equations are dependent.

From the given options, we can see the system of equations:

x − y = 2 and −2x + 2y = −4 are the same equation.

Take the equation −2x + 2y = −4 and divide by -2 on both sides, we get:

x - y = 2

This is the same equation as x − y = 2

Thus, the system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.

Answer:

In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.  

Step-by-step explanation:

Remember Generalization is like an inference.

You need to write a statement that is based on the given information about Anna's shapes.

_______________________________________________________

If we look at Anna's shapes we have 2 quadrilaterals and 1 triangle.

Then, the "following" shapes have the same properties meaning 2 quads and 1 triangle.

We can go straightforwardly by saying the shapes that Anna chose are 2 quadrilaterals and 1 triangle.

Parallel sides are only shown on 2 of the shapes (the square and the parallelogram).

There are 3 triangles: 1 right, 1 obtuse, and 1 equilateral or acute.

______________________________________________________
Here's my generalization:

If we look at the shapes that Anna chose, we can identify 2 quadrilaterals and 1 triangle. The following shapes don't belong with the ones she chose because there are 2 triangles (equilateral and one right triangle). Then, we have a square with 2 sets of parallel lines which the parallelogram has. The other quadrilateral doesn't have any parallel lines which can't be a trapezoid either. In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.  

Using perfect squares simplification, it is found that the value of the desired limit is of -4.

It is the value of a function as x approach

In this problem, the limit we want to find is given by:

[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2}[/tex]

If we just replace x by -2, we end with an undetermined limit, as we have 0/0.

However, the perfect square simplification states that:

a² - b² = (a - b)(a + b).

Hence:

x² - 4 = (x + 2)(x - 2).

Then:

[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2} = \lim_{x \rightarrow -2} \frac{(x + 2)(x - 2)}{x + 2} = \lim_{x \rightarrow -2} x - 2 = -2 - 2 = -4[/tex]

Hence, the value of the desired limit is of -4.

Answer:

x ≈ 45.6°

Step-by-step explanation:

using the Cosine rule in the triangle

cos x = [tex]\frac{8^2+15^2-11^2}{2(8)(15)}[/tex] = [tex]\frac{64+225-121}{240}[/tex] = [tex]\frac{168}{240}[/tex] , then

x = [tex]cos^{-1}[/tex] ( [tex]\frac{168}{240}[/tex] ) ≈ 45.6° ( to 1 dec. place )

Answer:

the answer is, area of the square - a half of area of the circle

C=circle and S =square

radius of C is 10

so Area Of C is =

[tex]\pi r^{2} = \pi{10}^{2} = 100\pi[/tex]

area of S = 10×10 = 100

so the answer is

[tex]s - \frac{c}{2} = 100 - \frac{100\pi}{2} = 100 - 50\pi[/tex]

Answer:

Step-by-step explanation:

this is two circles, one inside the other, circles have an area of pi*[tex]r^{2}[/tex] the flower bed is  20 meters in diameter or 10 meters in radius.

flower bed Area = 3.14*[tex]10^{2}[/tex]

flower bed Area = 314  [tex]m^{2}[/tex]

circle of sidewalk adds 3 meters

sidewalk circle area = 3.14*[tex]13^{2}[/tex]

sidewalk circle area = 530.66

subtract the flower bed area from the sidewalk area, and you have just the walk way it self.

530.66 - 314 = 216.66 [tex]m^{2}[/tex]   for the sidewalk only

Answer:

AC ≈ 12

Step-by-step explanation:

the angle between the tangent AC and the radius BC is 90°

then Δ ABC is right

note that BC = 9 ( radius of circle )

using Pythagoras' identity in the right triangle

AC² + BC² = AB²

AC² + 9² = (9 + 6)² = 15²

AC² + 81 = 225 ( subtract 81 from both sides )

AC² = 144 ( take square root of both sides )

AC = [tex]\sqrt{144}[/tex] = 12

Answer:

The area is 27m.

Step-by-step explanation:

We can first seperate this shape into two shapes. I seperated the 3x6 rectangle and the 3x3 square. Now we can find the area of these individual shapes. 3x3=9 and 3x6=18. We can now add these two numbers together to get the area of this shape. 9+18=27m. Therefore, the area of this shape is 27m.

Answer:

1. 600 cm^3

2. 24 cm^3

3. 540 cm^3

4. 1476 cm^3

Step-by-step explanation:

1. rectangular prism volume equation is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 5 x 8 x 15 and we get V = 600 cubic cm.

2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6 x 2 x 4 and we get V = 24 cubic cm

3. V = Bh, where B is the base area and h is the perpendicular height. V = 45(12). So, V = 540 cm^3

4. Same thing with this one: V = Bh. Substitute known values into this equation: V = 82(18), which means V = 1476 cm^3

Suppose the original fraction be x/y

Given, x : y = 2:3 ……(i)

then y = 3/2x

Now , by condition,

The coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

-4π/5

To find the coterminal angle, add and subtract by 2π in the angle -4π/5

Coterminal angle:

= -4π/5 - 2π

= -14π/5

= -4π/5 + 2π

= 6π/5

Reference angle:

= π - 4π/5  (as the angle lies in the second quadrant)

= π/5

Thus, the coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Answer:

30/45 or 2/3

Step-by-step explanation:

If you factor out a 10 from the numerator and a 9 from the denominator, you should get the following:

Numerator = 10 (a + b)

Denominator = 9 (x - y)

Since we know that (a + b) = 3 and (x - y) = 5, we can rewrite it as:

Numerator = 10(3)

Denominator = 9(5)

Therefore, the answer is 30/45, or 2/3.

Answer:

1000 cm²

Step-by-step explanation:

Given:

Formula:

[tex]\text{Volume = Length} \times \text{Width} \times \text{Height}[/tex]

Substitute the length, width, and the height of the prism to determine the volume of the prism.

[tex]\implies \text{Volume = 10} \times 12.5 \times 8[/tex]

Simplify the right hand side of the equation, as needed;

[tex]\implies \text{Volume = 10} \times 12.5 \times 8[/tex]

[tex]\implies \text{Volume =}\ 125 \times 8[/tex]

[tex]\implies \boxed{\text{Volume =}\ 1000 \ \text{cm}^{2} }[/tex]

Therefore, the volume of the prism is 1000 cm².
