What is the slope of the line passing through (-3, 5) and (5, -3)?

slope = -1
slope = 0
slope = 1
no slope

Answers

Answer 1

we know that

the formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

in this problem we have

[tex]A(-3,5)\ B(5,-3)[/tex]

substitute the values in the formula

[tex]m=\frac{-3-5}{5+3}[/tex]

[tex]m=\frac{-8}{8}[/tex]

[tex]m=-1[/tex]

therefore

the answer is the option

[tex]slope=-1[/tex]

Answer 2

Answer:

The Slope Is -1

What is 8 ÷ 9 equal I don't get it when my couculator says 0.99999888888888888???!!!

Answers

  "8 ÷ 9 = 8/9" ;  (as a fraction).

Using a calculator:  "8÷9 =                                         "0.88888888888...." ;   or; there may be a value such as:
__________________________________

"0.8888888888888889" ; There may be a "9" at the end;  that is; the calculator may round the value at the end.  
_______________________________________
I suggest recalculating the value on your calcutator.

Please sure to "clear" your calculator.  Usually this can be done by pressing the [AC] button ;  & then.  the [C] or [CE] button.

Then, try:  "8 ÷ 9" again.  You should get value similar to the correct answer; such as: 
______________________
       "0.88888888888" ; 

or:  "0.8888888888888889" .
______________________
Otherwise, there is a possibility that the calculator itself is damaged or broken (e.g. got "stepped on" or "heavy objects" were placed; and the "calculator buttons"/other internal parts of the calculator were damaged and are now malfunctioning).

How do you write 13/25 as a percentage

Answers

The fraction 13/25 is equivalent to 52 percent.
To workout this, divide the numerator by the denominator, sum this value to the integer part and multiply the result by 100%, so:
13/25 in percent = 13 ÷ 25 × 100% = 0.52 × 100% =  52%
13/25 as a percentage would just be 52%.

In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C.

Answers

because if the temperature was 29 degrees in july and in december it was 29 degrees less than 29 then that would be zero because 29-29=0
The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.

Triangles PQR and MNO are ( here it has a drop down menu I'll include those options below)
Similar or not similar?


Two right triangles, PQR and MNO. For triangle PQR, angle Q is thirty degrees. For triangle MNO, angle N is forty-five degrees.

Answers

Given that the two trianglea are right angles, this means that one of the angles is 90 degrees.

If one on the angles of triangle PQR is 30 degrees, then the third angle will be 60 degres.

Thus, the three angles of triangle PQR are: 90, 30, 60

If one on the angles of triangle MNO is 45 degrees, then the third angle will be 45 degres.

Thus, the three angles of triangle MNO are: 90, 45, 45

For two triangles to be similar, their angles has to equal.

Therefore, triangles PQR and MNO are not similar.
The triangles are not similar. For triangle PQR to be similar to triangle MNO, each angle would have to be congruent. The two triangles only have a 90 degree angle in common. Triangle PQR has 90, 30, and 60 degree angles while triangle MNO has 90, 45, and 45 degree angles.

How do you write 4500 in scientific notation

Answers

45 X 10^3

(forty-five times ten to the third)
First you would want to move a decimal place to the right one position(4,500, 4.500).

Then you are now going to want to count how many places to the right of the decimal ( there are 3 places to the right of the decimal).
 
So building upon what you know, you can now reconstruct the number into scientific notation. Now you are going to the decimal number 4.5 and times with 10 to the third power ( 10 ^3). Now to check your work to see if you did it correctly, you would do 10 to the third power equals 1,000 times 4.5 which equals 4,500 ( 10^3 = 1,000 x 4.5 = 4,500 or 4500.

The graph shows the total fare, y, for a taxi ride with respect to the miles traveled, x.



What is the slope and what does it represent?

Question 9 options:

The slope is 3 and it represents the cost per mile traveled.


The slope is 2.50 and it represents the total cost of the cab ride.


The slope is 0.40 and it represents the cost per mile traveled.


The slope is 2.50 and it represents the cost per mile traveled.

Answers

Final answer:

The slope of the graph, in this case, is 3 and it indicates the cost per mile traveled in a taxi. The slope is obtained by dividing the change in total fare by the change in miles traveled.

Explanation:

The correct answer is 'The slope is 3 and it represents the cost per mile traveled'. In this context, the slope of the graph represents the taxi fare rate per mile traveled, meaning for each mile you travel in the taxi, you are charged this amount. To find the slope (m), you usually use the formula m = change in y / change in x. Here, 'y' refers to the total fare, and 'x' refers to the miles traveled.

little time saver tip....notice that ur points have the same y value. This means that u have horizontal lines. Horizontal lines have a slope of 0 and are represented by y = a number..with that number being ur y coordinate in ur points.

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10. Is Jane correct? Explain your answer.

Answers

Jane is incorrect, this is because 3 factors of ten equals 1000(10*10*10=1000) and 100 is not equal to 1000 meaning you are not multiplying by the same number.

Answer:

Jane is incorrect.

Step-by-step explanation:

We have been given a statement. We are asked to determine whether the given statement is true or not.

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10.

[tex]\text{3 factor of 10}=10^3[/tex]    

[tex]\text{3 factor of 10}=10\times 10\times 10[/tex]

[tex]\text{3 factor of 10}=1000[/tex]

When we multiply a decimal by 100, it will move the decimal to two digits to right and multiplying a number by 1000 will the decimal to three digits to right.

Therefore, Jane is incorrect.

Michael's team won 60% of the 10 football games they played this season they lost the remainder of the games. how many games did Michael team lose?

Answers

60% of 10 is 6. 10 minus 6 is 4. Your answer is 4.
Hope this helped! :)

Final answer:

To find out how many games Michael's team lost, we can calculate the number of games they won and subtract it from the total number of games played.

Explanation:

To find out how many games Michael's team lost, we first need to calculate the number of games they won. We know that they won 60% of the 10 games, so we can calculate this by multiplying 10 by 0.6: 10 x 0.6 = 6. Therefore, Michael's team won 6 games. Since they won the remainder of the games, we can calculate the number of games they lost by subtracting the number of games they won from the total number of games played: 10 - 6 = 4. Therefore, Michael's team lost 4 games.

8x+15 = 2x+39

8x =2x+24

6x = 24

x = 24/6 = 4

 angle 4 = 2(4) +39 = 8+39 = 47

 angle 6 = angle 4

angle 6 = 47 degrees

m<6 = m<4  = 2x + 39              (vertical angles)
and m < 1  is also  = m<4       (corresponding angles)

Therefore  we have:-

2x + 39  = 8x + 15   Solving for x:-

2x - 8x = 15 - 39
-6x = - 24

x = 4

So the measure of <6 =  2(4) + 39  =  47 degrees.
