Step-by-step explanation:

Answer:

The slope of line is 1

Step-by-step explanation:

We need to find slope of line given points (16,1),(17,7)

The formula used to find slope of line is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given:

[tex]x_1=16, y_1=1, x_2=17 \ and \ y_2=7[/tex]

Finding slope using formula:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{7-6}{17-16}\\Slope=\frac{1}{1}\\Slope=1[/tex]

So, the slope of line is 1

Answer:

x=30

Step-by-step explanation:

a straight line is 180 degrees so to figure out x you would do 180-151 which equals 29 however if u plug 29 in for x it wouldn't work because (29-1) equals 28 and 151+28 do not equal to 180 degrees so x would equal 30 because (30-1) is 29

Step-by-step explanation:

straight line = 180°

x= 180 - 151 +1

x = 30

missing angle = x -1

= 30 - 1

= 29

Answer:

the first answer ( I think these are 3 different questions) is y = -4x + 7

the second answer is y = -3x + 5

the third answer is y = 6x - 5, because the lines are parallel, they have the same slope and the y int is -5 from the point given.

Answer:

y = (-7/5) x + 15

Step-by-step explanation:

Let's name the line whose formula we'll calculate as line A. The other line is line B.

Rewrite the equation of line B:

A parallel line has to have the same slope (-7/5). With that information in mind, we only need to calculate b (following the basic equation for a line, y=mx+b).

Line A passes through the point (5,8), so we can express the slope as:

So we solve for y₁:

That is the value in the Y-axis line A crosses when x=0. In other words, it is b.

The equation is y = (-7/5) x + 15

Change 25% to a decimal as step one.

So, 25% becomes 0.25.

0.25 means 25/100.

We can reduce 25/100 to the lowest terms.

Doing so, we get 1/4. Do you know how 25/100 becomes 1/4?

Look here:

We divide the numerator and denominator by the greatest common factor.

25÷ 25 = 1

100 ÷ 25 = 4

Thus, we get 1/4 as the final answer.

Is this in any way clear?

Answer:

x = 23

Step-by-step explanation:

You have to find where they are equal because the angle will be the same.

8x - 27 = 7x + 4

x = 23

The value of x is equal to 23°

Lines are straight and have negligible depth or width. There are a variety of lines you will learn about, such as perpendicular lines, intersecting lines, transversal lines, etc. An angle is a figure in which two rays emerge from a common point. You may also come across alternate and corresponding angles in this field.

Given here, Two corresponding angles thus they must be equal

Thus 8x-27=7x-4

            x= 23°

Hence, The value of x is equal to 23°

Answer:

  The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.

Step-by-step explanation:

The contribution margin of each necklace is the difference between its selling price (x) and its cost (2.75). Then the total profit from 8 necklaces would be ...

  8(x -2.75)

If Rita wants that profit to be $78, then she needs to solve the equation ...

  8(x -2.75) = 78 . . . . correct equation

The solution is ...

  x -2.75 = 9.75 . . . . divide by 8

  x = 12.50 . . . . . . . . add 2.75

She needs to sell each necklace for $12.50.

C - No, the graph does not make a straight line.

Step-by-step explanation:

Just did on edg

There is no proportional relationship between the time and the amount of popcorn popped.

No, the graph does not make a straight line.

Option C is the correct answer.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

A graph has minutes on the x-axis and ounces of popcorn on the y-axis and goes through the following coordinates.

(0,0), (50, 12), and (110, 18)

This means,

For 0 minutes, 0 ounces of popcorn.

For 50 minutes, 12 ounces of popcorn.

For 110 minutes, 18 ounces of popcorn.

50 minutes = 12 ounces

Divide 50 on both sides.

1 minute = 12/50 ounces

1 minute = 0.24 ounces ____(1)

110 minutes = 18 ounces

Divide 110 on both sides.

1 minute = 18/110 ounces

1 minute = 0.16 ounces ____(2)

From (1) and (2) we see that there is no proportional relationship between the time and the amount of popcorn popped.

Thus,

There is no proportional relationship between the time and the amount of popcorn popped.

No, the graph does not make a straight line.

Option C is the correct answer.

The required distance between points (-4,6) and (3, -7) is 14.8.

Given that,

To determine the distance between (-4,6) and (3, -7).

Coordinate, is represented as the values on the x-axis and y-axis of the graph

Here,

distance between (-4,6) and (3, -7) is given by the distance formula,
Distance = √[( x₁ - x₂ )² + ( y₁ - y₂ )²]
Distance = √[( -4 - 3 )² + ( 6 - (-7) )²]
Distance = √[( -7 )² + (13 )²]
Distance = √[49 + 169]
Distance = √218
Distance = 14.8

Thus, the required distance between points (-4,6) and (3, -7) is 14.8.

Answer:

true

Step-by-step explanation:

The given statement is true.

A credible source is one that is written by someone who is an expert in their discipline and is free of errors and bias.

Yes, identifying the purpose would increase the credibility of the source.

Including the intent of the information in the source will help place the information in a wider context - and often the context is necessary to fully understand the content of a source.

Otherwise, researchers or journalists would question the authenticity of the source. When doing research, it is very important to have enough credible sources to support the arguments of our work. So researchers need to double-check the validity of the information, make comparisons if necessary, that can prove the data included in the research is correct.
