Two equations for the constant of proportionality equal to 1/2

Mathematics
1 answer:
NemiM [27]3 years ago
5 0

y=kx and y=\frac{k}{x} are two equations of constant of proportionality

Step-by-step explanation:

          There are two equations for the constant of proportionality. That is

                       (i) Direct proportion

                       (ii) Inverse proportion

          In direct proportion y=kx, Now

                  if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.

         In Inverse proportion y=\frac{k}{x}, Now

                 if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.

         In direct proportion, we put y=1 and x=2, So k=\frac{1}{2}.

         So, the equations y=kx and y=\frac{k}{x} are two equations of constant of proportionality.

Answer:

C. 4/3x - 5

Step-by-step explanation:

First, to eliminate unnecessary answers, we can find out how to make sure the line will be perpendicular to -3/4. You will know if two lines are perpendicular if the slopes are COMPLETELY opposite. For example, 4/3 is COMPLETELY opposite from -3/4.

-3/4......4/3

So, now we know we eliminated two answers. We are left with A and C.

Then, I opened an online graphing calculator and found out which one of these lines pass through (12,9). Attached is a picture proving that answer C's line crosses through this point. Please mark me Brainliest; I need it to move on in my account! =D

When is the reciprocal of a fraction a whole number? Plz explain
Sati [7]

The reciprocal of a fraction is only a whole number when
the numerator of the original fraction is ' 1 ' or a factor of
the denominator (original fraction is not in simplest form).

Any other time, the reciprocal of the fraction is another fraction.
(It'll be an improper fraction, and can be written as a mixed number.)


The reciprocal of a fraction is just the same fraction
turned upside down.

-- The reciprocal of  1/5  is  5/1  or just  5 .
   (Original numerator is ' 1 '.)

-- The reciprocal of  5/25  is  25/5  or just  5 .
    (Original fraction is not in simplest form.)

--  The reciprocal of  5/7  is  7/5 , or  1 and 2/5 .

One triangle on a graph has a vertical side of 7 and a horizontal side of 12. Another triangle on a graph has a vertical side of
Darya [45]

Write a C program to compute Matrix Multiplication of two matrices. Use one dimensional array to store each matrix, where each row is stored after another. Hence, the size of the array will be a product of number of rows times number of columns of that matrix. Get number of row and column from user and use variable length array to initialize the size of the two matrices as well as the resultant matrix. Check whether the two matrices can be multiplied or not. Write a getMatrix() function to generate the array elements randomly. Write a printMatrix() function to print the 1D array elements in 2D Matrix format. Also, write another function product(), which multiplies the two matrices and stores in the resultant matrix. With SEED 5, the following output is generated.


Sample Output


Enter the rows and columns of Matrix A with space in between: 3 5


Enter the rows and columns of Matrix B with space in between: 5 4


Matrix A:


   8     6     4     1     6


   2     9     7     7     5


   1     3     1     1     2


Matrix B:


   9     5     4     5


   9     9     8     1


   4     4     3     5




   2     6     2     1


   4     5     2     4


Product AxB:


168   146   106    91


161   186   125    81


50    52    37    22


In conclusion, the answer is D; No, because they are not similar triangles.


Thank you, please give Brainliest! :)

Order the group of quadratic functions from widest to narrowest graph. y=6x^2

A ratio shows us the number of times a number contains another number. Monique should choose the third option.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

Given Monique prefers the ratio of multiple-choice questions to essay questions to be 4:1, Therefore, we can write,

Multiple choice questions/ essay questions = 4/1,

If we multiply both the numerator and the denominator by 6, the ratio will be,

Multiple choice questions/ essay questions = 4/1 × 1

Multiple choice questions/ essay questions = (4/1) × (6/6)

Multiple choice questions/ essay questions = 24 / 6

Thus, Monique should choose the third option.
