What are the slope and the y-intercept of the linear function that is represented by the equation 8x-2y = 5?

Answers

Answer:

The slope is 4 and the y intercept is -5/2

Step-by-step explanation:

8x-2y = 5

Solve for y to get the equation in slope intercept form

Subtract 8x from each side

8x-8x-2y =-8x+ 5

-2y = -8x+5

Divide by -2

-2y/-2 = -8x/-2 + 5/-2

y = 4x -5/2

This is in slope intercept form y= mx+b where m is the slope and b is the y intercept

The slope is 4 and the y intercept is -5/2

Which undefined term is used to define an angle?

line
plane
point
ray

Answers

The answer is point.

The undefined term is point.

What is an angle?

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.

Parts of an Angle

There are two main parts related to an angle - the arms and the vertex.

Arms of the Angle

The two rays which join at a common point to form the angle are called the arms of the angle. Observe the figure given below which shows that OA and OB are the arms of the angle AOB.

[tex]vertex[/tex]of the angle

[tex]vertex[/tex] is a common endpoint that is shared by the two rays. Observe the figure in which the [tex]vertex[/tex] O is marked as the joining point of the two arms.

Measure of an angle

An angle is measured in degrees. One full rotation around a point forms a complete angle of 360°.

As, the is defined on the basis of arms , vertices, measurement.

They all related to point and point doesn't have a particular definition.

Measurement question please show work thank you

Answers

Answers:

b)  92100 decimeters

c)   6650 decaliters

=====================================================

Work Shown for part b)

1 decameter = 10 meters

1 decimeter = 1/10 of a meter

10 decimeters = 1 meter .... multiply both sides by 10

100 decimeters = 10 meters ... multiply both sides by 10

100 decimeter = 1 decameter

921*(100 decimeter) = 921*(1 decameter)

92100 decimeters = 921 decameters

-------------------

Work Shown for part c)

We could follow the same idea as part b). I'm going to use another approach as shown in the diagram below. This conversion method is known as the railroad tracks method in some math textbooks.

Each column represents two things that are equivalent to one another. For example, 1 kiloliter is the same as 1000 liters. So each column, when you divide top over bottom, represents the value 1.

Notice the unit cancelations as shown by the color coding. The goal is to have every unit cancel except for the decaliters unit which is what we want to end up with ultimately.

Once you have the railroad tracks set up, you multiply straight across.

Along the top, we have 66.5*1000*1 = 66500

Along the bottom we have 1*10 = 10

Divide those results: 66500/10 = 6650

So 66.5 kiloliters converts to 6650 decaliters

Answer:

1) 92100 dm

2) 6650 decalitres

Henry and Liani have 200 feet of wood to frame a flower bed. Henry wants the bed to be a square, while Liani wants it to be a rectangle with dimensions of 55 feet and 45 feet. Which statement is true regarding the areas of the two flower beds? Henry's design would result in a larger flower bed because its area would be 2,500 square feet. Liani's design would result in a larger flower bed because its area would be 2,500 square feet. Henry's and Liani's designs would result in flower beds with the same area. Henry's and Liani's designs are not possible with the given amount of wood.

Answers

Answer:

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

Step-by-step explanation:

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

B. Liani's design would result in a larger flower bed because its area would be 2,500 square feet.

C. Henry's and Liani's designs would result in flower beds with the same area.

D. Henry's and Liani's designs are not possible with the given amount of wood.

Length of wood = 200 feet

Henry's square bed design = 200 feet / 4

= 50 feet

Note: A square has 4 equal sides, hence, the division by 4

Each side of the square bed = 50 feet

Area of the square bed = length ²

= (50 feet)²

= 2,500 square feet

Liani rectangular bed design

Length = 55 feet

Width = 45 feet

Note: adding of 2 length and 2 width = 200 feet

That is,

2(55) + 2(45)

= 110 + 90

= 200 feet of wood

Area of Liani rectangular bed design = length × width

= 55 feet × 45 feet

= 2,475 square feet

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

Answer: [tex]a_{n}=4n+-3[/tex]

Step-by-step explanation:

The way arithmetic sequences are usually written is:

[tex]a_{n} =a_{1} +(n-1)d[/tex]

[tex]a_{n}[/tex] is the the term you are looking for. It has an n because we aren't looking for a specific one.

[tex]a_{1}[/tex] is the first term of the sequence. In this case that is 1.

n is the term position. Meaning if you wanted to find the fifth term you'd sub 5 in for n.

d is the common difference. In this case it is 4.

Now we can sub these values in.

[tex]a_{n} =1 +(n-1)4[/tex]

We can simplify the right part of the equation.

[tex]a_{n} =1 +(n-1)4\\a_{n} =1 +(4)(n)-(4)(1)\\a_{n}=1+4n-4\\a_{n}=4n+1-4\\a_{n}=4n+-3[/tex]
