Answer:

7a+b-9c+17d

Step-by-step explanation:

-5 ( a-2b+3c -4d) - (-3) (4a -3b+2c-d)

Distribute

-5a+10b-15c+20d+12a-9b+6c-3d

Combine like terms

7a+b-9c+17d

7a + b - 9c + 17d

step-by-step explanation

(- 5)( a - 2b +3c - 4d ) - (-3)( 4a - 3b+2c - d )

- 5( a - 2b + 3c - 4d ) - (-3)( 4a - 3b + 2c - d)

Using Distributive property

- 5a + 10b - 15c + 20d + 12 a - 9b + 6c - 3d

Arranging like terms together

- 5a + 12a + 10b - 9b -15c + 6c + 20d -3d

7a + b - 9c + 17d

What does the point (200,90) represent?

Answers

Answer:

It represents 20 every 9

Step-by-step explanation:

(200,90) The 200 is on the x axis (horizontal, hotdog style), the 90 is on the y axis (vertical). Take whatever you have written on the bottom of the x axis (like feet) and whatever you have on the y axis like (time) and put them together into a sentence. Something like - "after 90 minutes (time) the whatever u r talking about traveled 200 feet (distance.)" <--- THIS IS JUST AN EXAMPLE DO NOT USE THIS.

It is difficult to answer this question without more context. Check the axes and write your answer based on whatever they say.

the image below, what is true about angles 1, 2, and 3?

A. 3 = 37
B. 1 = 37
C. 2 = 37

Answers

Answer:

C. 2 = 37

Step-by-step explanation:

<2 and 37 are vertical angles and vertical angles are equal

Angle 1 and 37 form a straight line so they add to 180

<1 + 37 = 180

<1 = 180-37 = 143

Angle 3 and 37 form a straight line so they add to 180

<3 + 37 = 180

<3= 180-37 = 143

answer is C 2= 37 because the angle properties says that if it is an opposite angle it has the same angles..

On a coordinate plane, a line goes through points (0, 1) and (4, 2). What is the slope of the line? m =

Answers

Answer:

m= [tex]\frac{1}{4} \\[/tex]

Step-by-step explanation:

Use the slope formula to get your answer. (m = y₂ - y₁ / x₂ - x₁ )

x₁ = 0

y₁ = 1

x₂ = 4

y₂ = 2

When you insert them into the formula, you get

m= [tex]\frac{2 - 1}{4 - 0}[/tex]

which equals [tex]\frac{1}{4}[/tex].

the answer would be 1/4

Find the mean, median, and mode of the data set. Round to the nearest tenth.

5, 7, 2, 6, 7, 10, 12, 7, 9, 13, 5

Answers

Answer:

The mean is 7.5.

The median is 7.

The mode is 7.

Step-by-step explanation:

To find the mean, add up all the numbers in the data set and then divide the sum by the total number of values.

5 + 7 + 2 + 6 + 7 + 10 + 12 + 7 + 9 + 13 + 5 = 83

83 divided 11 equals 7.5.

To find the median, arrange all the numbers in the data set from smallest to largest and then find the number that is in the middle of the set.

To find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.    

the mean is 7.5 the median is 7 and more is 7

The number without the variable (the letter x) is referred to as the y intercept. Therefore, it refers to the point along the y axis (up and down). For instance, in the first problem, the y intercept is -3. You would then go down 3 spaces and draw in the point.

The slope always has the x variable next to it. For instance, the slope of the first question is (positive) 2. To graph that, you would go up 2, and to the right one. Then you would repeat.

Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5

Answers

Answer:

C. y = 1/2x + 5

Step-by-step explanation:

For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.

For D. it doesn't even have x in it, so basically y equals a number.

C. is a linear equation, y = 1/2x + 5

The answer is C: y= 1/2 x +5

This is because any slope to a certain power would make it an exponential function.

C. y= 1/2 x + 5 is not to any power, making it linear

What is a tetrahedron?

A tetrahedron is a polyhedron having four faces, six edges, and four vertices, all of which are triangles. It is also known as a triangular pyramid with a triangle base.

The ABCDEFGH is a rectangular prism given in the question, which has :

CD = 5, AD = 6, and AE = 8

We have to determine the volume of tetrahedron ABCF.

As per the question, the required solution would be as:

The volume of tetrahedron ABCF = 1/3 × 1/2 × 5 × 6 × 8

Apply the multiplication operation, and we get

The volume of tetrahedron ABCF = 40 cube units

Thus, the volume of the given tetrahedron ABCF will be 40 cube units.

Conceptually, an integer is odd if it has a remainder of 1 when dividing by 2. And an integer is even if it has a remainder of 0 when dividing by 2.But when proving something rigorously, mathematicians use more precise definitions, like these: an integer is odd if it can be written in the form 2k + 1, where k is some integer. An integer is even if it can be written in the form 2k, where k is some integer. For example, 13 is odd because 13 can be written as 2(6) + 1.With these definitions, use complete sentences to explain why zero is an even number.
